PROBLEM TO BE SOLVED: To convert a photoreceptor drum and a developing unit, in from a noncontact state to the contact state using through a simple operation, without adopting components such as a stopper. SOLUTION: This toner cartridge, provided with a handle 5, that is a holding hand for handling the toner cartridge of the electrophotographic recording device composed by the developing unit 3, provided with a developing roller 2 and the photosensitive unit 4 provided with the photosensitive drum 1, brings the photoreceptor drum 1 into a state of noncontact with the developing roller 2 by inclining pushing down a knob part 15 of the handle 5, and into a state of being in press contact with the same by erecting the knob. The developing unit 3 swings around a swinging fulcrum shaft 6, a spring 12 energizes a roller 20 so as to press the developing roller 2 held in contact against the photoreceptor drum 1. |
