Process cartridge, electrophotographic image forming apparatus and electro- photographic image forming apparatus transmissions method

摘要

A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus includes a cartridge frame; an electrophotographic photosensitive drum (1); a cleaning member for removing toner remaining on said electrophotographic photosensitive drum; a transporting member for transporting the toner removed from said electrophotographic photosensitive drum by said cleaning member; a positioning portion for positioning said process cartridge when said process cartridge is mounted to a mounting position of the main assembly of said apparatus, said positioning portion being engageable with a main assembly positioning member provided in the main assembly of said apparatus, and being projected from said cartridge frame coaxially with said electrophotographic photosensitive drum at one longitudinal end side of said electrophotographic photosensitive drum; a drum driving force receiving member (23) for receiving driving force for rotating said electrophotographic photosensitive drum for the main assembly when said process cartridge is mounted to the mounting position of the main assembly, said drum driving force receiving member being juxtaposed with said positioning member coaxially with said electrophotographic photosensitive drum and being projected outwardly beyond said positioning member; a transporting member driving force receiving member (44) for receiving driving force for rotating said toner transporting member from the main assembly when said process cartridge is mounted to the mounting position of the main assembly, wherein said transporting member driving force receiving member (44) is disposed at the same cartridge frame side as a side where said drum driving force receiving member (23) is disposed in the longitudinal direction of said electrophotographic photosensitive drum (1).
