Abstract:
A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus, said process cartridge comprising:an electrophotographic photosensitive drum; process means actable on said electrophotographic photosensitive drum; and a load producing member configured and positioned to impart a load on a peripheral surface of a cylindrical member rotatable with said electrophotographic photosensitive drum to increase the rotational torque required for rotation of said electrophotographic photosensitive drums, wherein said load producing member is provided at one axial end of said electrophotographic photosensitive drum, said load producing member including a spring member configured and positioned to tighten on the peripheral surface of the cylindrical member, a housing member engaged with a cartridge frame and supporting said spring member, and an inclined portion which is configured and positioned to provide said electrophotographic photosensitive drum with a rotational load by a frictional force produced between the cylindrical member and said spring member and to contact the cartridge frame to produce a force in an axial direction.
