Abstract

PURPOSE:To prevent the deterioration in image quality by providing a photosensitive drum, a developing device which develops the latent image formed on said photosensitive drum, a cleaning device, etc. which removes the remaining toner stuck on the photosensitive drum. CONSTITUTION:A copying device is movided with a developing device 3 which develops the latent image formed on the surface of a photosensitive drum 1 and a cleaning device 8 which removes the remaining toner stuck on the drum 1. The toner remaining on the surface of the photoreceptor 1 after transfer is scraped off by a cleaning blade 9 in the device 8 of a blade type and is collected in the lower part of the device 8. There is a toner conveyance means 10 in said part, by which the toner is conveyed in the direction toward this side. The toner is conducted smoothly to the developing device without sticking and entry of the powder of paper in the developing device and the deterioration in the image quality are obviated according to the abovementioned invention.
