The development cartridge may be mounted in the main body of the electrophotographic image forming apparatus with its development nip control member being in the first position, separating the photoconductive member from the developing roller. The electrophotographic image forming apparatus may be packaged for distribution with the development cartridge received in the main body thereof where the photoconductive drum and the developing roller are no in contact with each other in the development cartridge as packaged.
