    Abstract: An image forming apparatus includes a change processing portion, a detection processing portion, a second acquisition processing portion, and an adjustment processing portion. The change processing portion changes a transfer current when a plurality of specific toner images which each include a toner layer of C formed on an image-carrying member and a toner layer of M are each transferred to a sheet. The detection processing portion detects a specific image that corresponds to each specific toner image included in the captured image of the sheet. The second acquisition processing portion acquires, for each of detected specific images, a skewness of a histogram of gradation values of a color mixture of M and Y in pixels included in each of the specific images. The adjustment processing portion adjusts the transfer current based on: the skewness acquired for each of the specific images; and the transfer current corresponding to the skewness.

    Abstract: An image forming apparatus includes an image carrier, a rotating brush, a collecting roller, a cleaning blade, a sealing member and a side sealing member. The sealing member has an extension part extending outside from each end of the collecting roller in an axial direction. The sealing member comes into contact with the collecting roller between a contact area between the rotating brush and the collecting roller and the cleaning blade and then prevents backflow of the residue. The side sealing member lifts the extension part toward the collecting roller on an outside at a predetermined interval from a position corresponding to each side edge of a maximum-width sheet passing region on the image carrier.

    Abstract: An image forming apparatus includes a plurality of image carriers, a charging device, an exposure device, a development device, and an intermediate transfer belt. The image carrier has a surface on which an amorphous silicon photosensitive layer is formed. The intermediate transfer belt is a plastic belt having a surface resistivity of 9.5 to 10.5 (log Ω/square). An offset amount of the primary transfer roller from the image carrier is 0 to 2 (mm), a contact surface pressure between the image carrier and the intermediate transfer belt is 0.5 to 1.5 (gf/mm2), and a charge density of primary transfer current that flows when the primary transfer voltage is applied to the primary transfer roller is 0.016 to 0.040 (μC/cm2).

    Abstract: An image forming apparatus includes an image forming portion, a first acquisition processing portion, a second acquisition processing portion, and an adjustment processing portion. The image forming portion forms an image on a sheet. The first acquisition processing portion acquires a captured image of the sheet. The second acquisition processing portion acquires a specific value that indicates a difference between a gradation value of a pixel that, among pixels included in the captured image acquired by the first acquisition processing portion, corresponds to a higher part of an outer surface of the sheet, and a gradation value of a pixel that, among the pixels included in the captured image, corresponds to a lower part that is lower than the higher part. The adjustment processing portion adjusts an image forming condition of the image forming portion based on the specific value acquired by the second acquisition processing portion.

    Abstract: An image forming apparatus of the present disclosure includes a plurality of image forming portions, an intermediate transfer unit, a secondary transfer member, a belt cleaning device, and a control portion. The intermediate transfer unit includes an intermediate transfer belt, a plurality of primary transfer members, a drive roller, a tension roller, and a contacting/separating mechanism. The belt cleaning device includes a cleaning member which faces the tension roller with the intermediate transfer belt therebetween. In a withdrawal mode, the cleaning member is moved by pressing force of the tension roller further into a housing from an opening portion as compared with in a printing mode. The control portion is capable of executing, while image formation is not being performed, a transfer toner collection mode in which the intermediate transfer belt and the belt cleaning device are driven in the withdrawal mode.
