ABSTRACT:
An assembling method of a process cartridge detachably mountable to an image forming apparatus includes providing a drum frame, supporting an photosensitive drum and having first and second engaging portions above the electrophotographic photosensitive drum, one adjacent each longitudinal end of the electrophotographic photosensitive drum; and providing a developing device frame supporting a developer, and having first and second compression springs above the developer, one adjacent each longitudinal end of the developer, and first and second projected portions projected in a direction crossing with a longitudinal direction of the developer, one adjacent each longitudinal end of the developer. The first and second projected portions are engaged with the first and second engaging portions, respectively. A first penetrating member is penetrated through a first opening formed in the first projected portion and a third opening formed in the first engaging portion, and a second penetrating member is penetrated through a second opening formed in the second projected portion and a fourth opening formed in the second engaging portion, while the projected portions and the engaging portions are engaged with each other.
