PROBLEM TO BE SOLVED: To recycle toner by composing a developing means so that it is attached/detached to/from the inside of the device integrally with a photoreceptor and its cleaning means, and carrying waste toner recovered by the cleaning means of the photoreceptor and the cleansing means of an intermediate transfer body set in the device, to the developing means. SOLUTION: On the front of a cartridge 30 a toner carrying pipe 50A is set to connect the cleaner 19 of the photoreceptive drum 10 and the developing unit 13, which re housed in it. Further, on the back of the rear substrate 40B of the main body of the device, a toner carrying pipe 50B is set to connect its one end to the cleaner 140 of the toner-image receiving body 14a and to connect its other end to the cleaner 19 separably. Accompanying the attachment/ detachment of the cartridge 30, the connection parts of the carrying pipe 50B and cleaner 19 are automatically joined and opening or separated for closing. |
