Abstract: A driving transmission device includes a storage part, a fixing pin and a supporting part. The storage part has a through hole. The fixing pin rotatably supports a gear. To the supporting part, the fixing pin is fixed. A hole side chamfered portion is formed at an outside opening edge of the through hole. A shaft side chamfered portion is formed at the tip end portion of the fixing pin. A lubricant is applied to a contact area between the fixing pin and the through hole. A hole side boundary portion between an inner circumferential surface of the through hole and the hole side chamfered portion is in contact with an outer circumferential surface of the fixing pin. A shaft side boundary portion between an outer circumferential surface of the fixing pin and the shaft side chamfered portion faces the hole side chamfered portion with a gap.

Abstract: A fixing device includes a fixing member, a pressure roller, a discharge rollers pair, a discharge guide, and an actuator. The fixing member is heated by a heat source. The pressure roller forms a pressurized region. The discharge rollers pair includes an upper roller and a lower roller, and conveys the sheet passed through the pressurized region. The discharge guide guides the sheet passed through the pressurized region to the discharge rollers pair. The actuator includes a rotating shaft supported by the discharge guide rotatably and movably in an axial direction and a detection piece extending radially from the rotating shaft, and rotated by the sheet passed through the pressurized region to detect the sheet. The discharge guide has a slit in which the detection piece is housed to regulate a moving of the detection piece in a width direction of the sheet.

Abstract: A floating body is stored in a tank with a coolant and has a lower density than the coolant. A swing member is swingably supported and includes a contact portion which is displaced by being brought into contact with the tank and a to-be-detected portion which moves in an interlocking manner with the displacement of the contact portion. A sensor detects the floating body or the to-be-detected portion present at a detection position. The tank includes a restriction portion which restricts a movable range of the floating body to a range in which the detection position is a lower limit. By the attachment of the tank to the attachment portion, the to-be-detected portion is displaced from the detection position to an evacuation position in the interlocking manner with the displacement of the contact portion.

Abstract: An inkjet recording apparatus includes a recording head, a waste ink container, and a suction mechanism. The waste ink container has a plurality of receiving ports to receive ink, a suction port, and a plurality of suction air passages configured to communicate between a destination receiving port and the suction port. The suction air passages include a plurality of first air passages connected to one first receiving port, and a plurality of second air passages respectively connected to a plurality of second receiving ports, so as to extend to the suction port. The plurality of first air passages respectively join the second air passages different to each other, so as to communicate between the first receiving port and the suction port.

Abstract: A transport device includes a transport mechanism and a carry in/out mechanism. The transport mechanism transports a recording medium from inside of an image forming apparatus that forms an image on the recording medium, to outside of the image forming apparatus, and transports the recording medium carried in from the outside of the image forming apparatus, to the inside thereof. The carry in/out mechanism performs, in a linked manner, an operation including receiving the recording medium transported by the transport mechanism toward the outside, and further transporting the recording medium toward the outside of the image forming apparatus, and an operation including receiving the recording medium carried in from the outside, and further transporting the recording medium toward the transport mechanism.

Abstract: A process unit includes a unit frame detachable from a main body frame, a plurality of development cartridges mounted so as to be mutually independently attachable and detachable with respect to the unit frame, and a lock mechanism. The lock mechanism has a lock member that restrains movement of the unit frame by being held at a first position at which the lock member is engageable with the main body frame. The lock member is caused, by all the development cartridges being detached from the unit frame, to shift from the first position to a second position at which the lock member does not engage with the main body frame.
