PURPOSE:To reduce the light quantity of an eraser lamp by giving conductivity to a blade which wipes the surface of a photosensitive body in an electrophotographic copying machine and earthing it. CONSTITUTION:A blade made of conductive elastomer is used as the blade 8, which is earthed. After a photosensitive drum 1 is electrostatically charged by a charger 2 and data is written on the surface with a laser beam from a light source 3, a latent image is developed by a developing device 4 and a toner image 5 is formed on the photosensitive drum 1. The toner image 5 is transferred to paper by a transfer charger 6 and residual toner 7 is left on the drum 1. The residual toner 7 is scraped by the blade 8 and accumulated in a toner box 9. Thus, a cleaning effect is improved and the light quantity of an eraser can be reduced. |
