ABSTRACT:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, wherein said main assembly includes a motor, a main assembly side gear for receiving driving force from said motor and a hole defined by twisted surfaces, said hole being substantially coaxial with said gear, said process cartridge includes an electrophotographic photosensitive drum; process means actable on said photosensitive drum; a projection engageable with said twisted surfaces, said projection being provided at a longitudinal end of said photosensitive drum, wherein said projection is non-twisted, and when said main assembly side gear rotates with said hole and projection engaged with each other, rotational driving force is transmitted from said gear to said photosensitive drum through engagement between said hole and said projection; and a resilient member for urging said process cartridge in a longitudinal direction of said photosensitive drum when said process cartridge is mounted to the main assembly.
