摘要： A process cartridge is detachably mountable to a main assembly of the electrophotographic image forming apparatus. The main assembly includes first and second transmitters, a cartridge positioner, a movable member, and a lock. The cartridge includes a photosensitive drum, a developing roller, a drum coupler transmitting a first driving force to the drum of the mounted cartridge and a shaft coupler, transmitting a second driving force from the second transmitter with a deviation permitted between axes of the second transmitter and the roller. The shaft coupler includes an engager engaging the second transmitter and receiving the second driving force for the mounted cartridge. When the cartridge is moved by the movable member, the engager is positioned to the lock and the distance between the engager and roller axes is smaller when the cartridge is positioned to the positioner than when the engager is positioned by a cartridge holding portion.

摘要： A pressing member (138) applies a pressing force to a trailing end of a photosensitive-member unit (21) in a direction (F) which intersects a predetermined reference direction (F1), allowing the pressing force to have both a first component (F1) in the predetermined reference direction (F1) and a second component (F2) perpendicular to the predetermined reference direction (F1). A trailing end is pressed in the predetermined reference direction (F1) by the first component. In the mounted state, the leading end is in contact with the reference member (125) at two contact surfaces including a first contact surface (113) and a second contact surface (114). The first contact surface (113) defines a first positioning direction being perpendicular to the first contact surface (113) and intersecting the predetermined reference direction (F1). The second contact surface (114) defines a second positioning direction being perpendicular to the second contact surface (114) and intersecting both the predetermined reference direction (F1) and the first positioning direction, allowing the photosensitive-member unit (21) to be positioned with respect to the main body (2).
