Abstract: Provided is a developing cartridge including a photosensitive unit and a developing unit connected to each other to rotate to a developing location and a non-developing location. An elastic member applies an elastic force to the developing unit and the photosensitive unit in a direction of rotating to the developing location. The developing cartridge includes a nip separating portion switched to a nip forming location where the developing unit is located at the developing location and to a nip separating location where the developing unit is located at the non-developing location, a manipulation portion for switching the nip separating portion to the nip forming location and to the nip separating location by a manual manipulation, and a nip forming unit for switching the nip separating portion from the nip separating location to the nip forming location as the photosensitive unit and the developing unit start to operate.
