Abstract
Disclosed in the present invention is a process cartridge, which is detachably mounted into an electronic imaging device, wherein the electronic imaging device comprises a separating member. The process cartridge comprises: a photosensitive drum; a developing roller; a first housing supporting the developing roller, wherein when the process cartridge is mounted into the electronic imaging device, in a direction of gravity, the photosensitive drum is located on a lower end side of the process cartridge, and an axis of the developing roller is located on an upper side of an axis of the photosensitive drum; and an integrally molded second housing. The second housing supports the photosensitive drum. A first housing is rotatable relative to the second housing. A separating force receiving component movable relative to the second housing is provided on the second housing. The separating force receiving component receives a force from the separating member to move, and the movement of the separating force receiving component drives the first housing to move relative to the second housing, so that the developing roller is separated from the photosensitive drum.
