ABSTRACT:
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.
