PURPOSE:To simplify a mechanism and to miniaturize a device by integrally installing a cleaning member for removing residual developer remaining on the surface of a photosensitive body and cleaning the surface of the photosensitive body in a developing device. CONSTITUTION:This device is provided with a toner holding body which is arranged on the opening part 3a of a developing vessel 3 in the developing device 2 and opposite to the photosensitive drum 1, a doctor blade 6 fixed under the toner holding body, and the cleaning member 7 arranged above the toner holding body, besides, the device is provided with a toner recovering part 8 installed on the right side of the cleaning member 7 in the developing vessel 3, and a holding member 9 for holding the cleaning member 7 in the toner recovering part 8. The toner holding body is constituted of a magnetic roller 5a and a developing sleeve 5b for covering the magnetic roller 5a therewith, and the residual toner removed from the surface of the photosensitive body by the cleaning member 7 is carried and recovered in the developer recovering part 8 by the actuation of an alternating field which is generated by rotating the magnetic roller 5a. |
