The force receiving member provided in the developing cartridge 1 in cooperation with the force applying assembly in the image forming apparatus can accomplish switching between the contact and separation states of the developer bearing member 2 in the developing cartridge 1 and the image bearing member 51 in the photosensitive cartridge 50. Due to the arrangement of the mounting shafts 1a and 1b, the relative rotational positions of the developing cartridge 1 and the photosensitive cartridge 50 are more accurate in each separation and contact process of the developer bearing member 2 in the developing cartridge 1 and the image bearing member 51 in the photosensitive cartridge 50, so that the accurate contact of the developer bearing member 2 and the image bearing member 51 is ensured, and the developing and imaging effects are improved.
