摘要： A process cartridge having an insertion construction for a connecting pin swingably supporting a developing unit where there are achieved an improvement in assembly property, a minimization of container deformation, and prevention of coming-off of the connecting pin due to a small press-fitting region. The connecting pin swingably supporting the developing unit is formed of a styrene-based resin composite, and, by injecting a terpene solvent from a cutout of a photosensitive drum unit frame to the outer periphery of the connecting pin, integral connection is effected between the photosensitive drum unit frame and the connecting pin, and further, between the photosensitive drum unit frame and a drum bearing member. Due to a press-fit portion between the connecting pin and the photosensitive drum unit frame, no terpene solvent flows to the developing unit side.

摘要： A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The cartridge includes an electrophotographic photosensitive drum, a developing roller, a drum unit containing the drum, a developing unit containing the roller and being movable so the roller contacts and is spaced from the drum, and a first force receiver receiving a force from a main-assembly first force applier by movement of a door from open to closed positions when mounting the cartridge and a second force receiver movable from a stand-by position by movement of the first force receiver by a force received from the first force applier. The second force receiver takes a projected position receiving a force from the second force applier to move the developing unit so the roller moves out of contact with the drum, the projected position being higher than the stand-by position.
