Abstract: The history record unit, in the non-volatile storage device, records recovery history information showing a history of the recovery process. The suspension control unit, when the recovery process' frequency specified based on the recovery history information exceeds a first reference frequency, restricts execution of the specific suspension process which is in response to a satisfaction of the suspension condition. Further, the suspension control unit, when the recovery process' frequency specified based on the recovery history information is lower than a second reference frequency, which is lower than the first reference frequency, under a situation where the specific suspension process' execution is restricted, cancels the restricting of the specific suspension process' execution.

Abstract: A toner conveying device (7a to 7d) includes a toner conveying path (26), a conveying screw (29), and a flicker (31). The conveying screw (29) includes a rotation shaft (29a) and a helical blade (29b) formed on an outer circumferential surface of the rotation shaft (29a). The flicker (31) includes a plurality of first contact pieces (33) that press the conveying screw (29) in a first direction toward a bottom of the toner conveying path (26), and a plurality of second contact pieces (34) that contact the conveying screw (29) from a side opposite to the first contact pieces (33) and press the conveying screw (29) in a second direction opposite to the first direction. A force with which the first contact pieces (33) press the conveying screw (29) is greater than a force with which the second contact pieces (34) press the conveying screw.

Abstract: A sorter includes a plurality of sheet output trays, a first actuator, a transferring mechanism, a control device, and a plurality of tray full detection mechanisms. The first actuator travels along the plurality of sheet output trays to guide a sheet onto any one of the plurality of sheet output trays. The transferring mechanism transfers the first actuator. The control device controls an operation of the transferring mechanism. The plurality of tray full detection mechanisms are provided one for each of the plurality of sheet output trays. Each of the plurality of tray full detection mechanisms includes a second actuator and a tray full detection sensor. The control device identifies an actual location of the first actuator based on a change of a detection signal produced by a change in attitude of the second actuator due to transfer of the first actuator and output from the tray full detection sensor.

Abstract: A device diagnosis system includes an image forming apparatus, a portable terminal device, and an abnormal noise decision device. The portable terminal device collects an operating sound of the image forming apparatus, at a sound collecting position selected from a plurality of predetermined sound collecting positions relative to the image forming apparatus. The abnormal noise decision device (a) identifies a decision criterion corresponding to the sound collecting position, and (b) decides whether the operating sound contains an abnormal noise, on a basis of acoustic data of the operating sound collected, in accordance with the decision criterion identified.

Abstract: The fixing device includes: a rotatable endless fixing belt; a heater that heats the fixing belt; a holding member that holds the heater so that a front surface thereof is in contact with an inner peripheral surface of the fixing belt; and a pressure member that is pressed against the heater with the fixing belt therebetween and to form a pressure area between the pressure member and the fixing belt where a sheet to which a toner image has been transferred is heated and pressed. A uniform heating layer is formed on a rear side of the heater without any gaps.

Abstract: A recording head ejects ink using nozzles. A control unit determines nozzles corresponding to an image to be printed and causes the recording head to eject ink from the nozzles. A correction processing unit detects an ejection malfunction nozzle and performs a correction process corresponding to the ejection malfunction nozzles. The correction processing unit causes a secondary adjacent nozzle of the ejection malfunction nozzle to perform ink ejection with a first ink ejection amount if ink ejection of a primary adjacent nozzle of ejection malfunction nozzle is performed earlier than ink ejection of the secondary adjacent nozzle and causes the secondary adjacent nozzle to perform ink ejection with a second ink ejection amount if ink ejection of the primary adjacent nozzle is performed later than ink ejection of the secondary adjacent nozzle. Here, the second ink ejection amount is smaller than the first ink ejection amount.

Abstract: An image forming apparatus includes a drum unit, a developing unit, a developing roller bearing, a guide portion, and an urging portion. The drum unit includes a photosensitive drum. The developing unit includes a developing roller. The developing roller bearing supports the developing roller and can move radially and rotate axially with respect to the developing unit. The guide portion is formed in the drum unit and guides the developing roller bearing in directions toward and away from the photosensitive drum. The urging portion urges the developing unit in such a direction that it presses the developing roller against the photosensitive drum. The developing unit includes a restriction portion that restricts the rotation of the developing roller bearing with respect to the developing unit within a predetermined range.

Abstract: A sheet post-processing apparatus (1) includes a processing tray (5), a sheet discharge port (7), a conveyance rollers pair (4), lower and upper discharge rollers (81), (82) and a discharge tray (9). When the sheet having a folded portion is stacked on the processing tray (5) with the folded portion downward, a controller rotates the lower and upper discharge rollers (81), (82) to advance the folded portion to the sheet discharge port (7), stops the lower discharge roller (81) before the folded portion passes the sheet discharge port (7), rotates the conveyance rollers pair (4) and the upper discharge roller (82) so as to convey the rear half portion to the downstream side until the sheet passes the conveyance rollers pair (4) and to form a deflection on the sheet, rotates the lower and upper conveyance rollers (81), (82) and then to stack the sheet on the processing tray (5).

Abstract: An image forming apparatus includes an image forming portion, an exposure device, an image density sensor, and a control portion. The control portion can, by adjusting the development voltage based on the image density of a reference image and the amount of exposure from the exposure device, perform image density correction to adjust the image density. The control portion predicts the toner charge amount based on a formation condition of the reference image and the image density of the reference image and determines the timing of performing the image density correction next time based on the rate of change of the toner charge amount calculated using a first toner charge amount predicted when the image density correction was performed last time, a second toner charge amount predicted when the image density correction is performed this time, and the interval between the image density correction performed last time and this time.
