摘要： A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus including a movable member movable from an outside of the main assembly of the apparatus to an inside thereof while carrying the process cartridge. The cartridge includes a drum, charging and developing rollers, rotatably connected first and second frames supporting different rollers, drum and developing roller driving force receiving portions, first and second portions-to-be-supported, on one and the other ends of the first frame, first and second portions-to-be-positioned, on one and the other ends of the first frame positioned to first and second main assembly side positioning portions during a lowering movement of the movable member toward a transfer belt, charging and developing bias contacts exposed at the other end, and a portion-to-be-urged, on the first frame upper surface for receiving an elastic force to position the process cartridge relative to the main assembly.
