A process cartridge includes an image carrier unit which is equipped with an image carrier, on which an electrostatic latent image is formed, and a developer supply unit which supplies developer to the image carrier unit 11. The image carrier unit and the developer supply unit are configured to be attached and detached with respect to an apparatus main body in which the units are accommodated. Electrical contacts are provided to form electrical connection between the image carrier unit 11 and the developer supply unit 9 in a mounted state in the apparatus main body.

A reciprocating-motion converting mechanism includes a cam that rotates around a rotation center; a reciprocating member that is reciprocated due to rotation of the cam; and a pressing unit that presses the reciprocating member to the cam. A first load torque is generated by a load applied at a point of contact of the cam and the reciprocating motion member. A load applying unit applies a load to the cam to generate a second load torque having a phase substantially opposite to a phase of the first load torque.

Plural auxiliary rotating members abut at different positions in a circumferential direction of a roller-shaped rotating member that is configured to rotate in a forward direction and a reverse direction. Diameters of a portion of the roller-shaped rotating member where a first auxiliary rotating member abuts and a portion of the roller-shaped rotating member where a second auxiliary rotating member abuts are different from each other. Conveying speeds of sheets conveyed by the first auxiliary rotating member and the second auxiliary rotating member with the roller-shaped rotating member in different directions at the same time are different from each other.

When starting driving of an agitating unit or a developing roller in an image forming apparatus, rotation speed of one or both of the agitating unit and the developing roller is raised in a stepwise manner until the agitating unit and the developing roller attain a steady rotation speed. When stopping the driving of the agitating unit or the developing roller, the rotation speed is lowered in a stepwise manner until completion of stop of the driving.

A drive transmission device, which is included in an image forming apparatus, includes a drive transmission body to which a drive force is applied from a driving source, and a rotary shaft having a press-in portion mounted on one end thereof in the axial direction. The press-in portion has multiple planes disposed parallel to an axial direction and configured to receive the drive transmission body. The multiple planes include upstream and downstream side planes disposed downstream from the upstream side plane in a press-in direction of the drive transmission body. The upstream and downstream side planes are aligned along the press-in direction of the drive transmission body and have respective distances different from each other from an axial center of the rotary shaft. A distance from the downstream side plane to the axial center is greater than a distance from the upstream side plane to the axial center.

A moving device assembly includes a moving device and a shield. The moving device is movable between a first position and a second position, to move a detector including a detection surface relative to an opposing member disposed opposite the detector. The shield shields the detection surface of the detector. As the moving device is at the first position, the detector is at a proximal position at which the detector is near the opposing member, and as the moving device is at the second position, the detector is at a shield position at which the detector is separated from the opposing member and the detection surface of the detector is shielded by the shield.

An image forming apparatus includes an image bearer, an image forming unit, an intermediate transfer member, a secondary transfer member, an image detector, a computing device, and a conveyor device. The computing device calculates a traveling speed of the intermediate transfer member based on detection information provided by the image detector. The conveyor device continuously transports to a secondary transfer portion a plurality of recording media one by one at a predetermined interval between successive recording media. The image forming unit forms a test image at a space between successive recording-medium contact regions of the intermediate transfer member at which the recording medium contacts the intermediate transfer member. A travel distance of the intermediate transfer member from the detection position on the intermediate transfer member to the secondary transfer portion in a traveling direction thereof is shorter than the space between the successive recording-medium contact regions.
