PURPOSE:To simplify a device and reduce the cost by adhering a rubber blade, where plural needle electrodes are buried, to a conductive elastic member connected to a power source and connecting electrically needle electrodes to the conductive elastic mamber. CONSTITUTION:A rubber plate 14 where plural needle electrodes 16 are buried is adhered to a conductive elastic member 18, and the front end of the rubber blade 14 is slided on a photosensitive drum 2. The conductive elastic member 18 has one end supported by a holder 20 and is connected to a voltage source 22 to impress a DC or an AC to needle electrodes 16. The impressed voltage is about 200-3,000V. Thus, the photosensitive drum is cleaned well even if a precleaning corotron is omitted, and the structure is simplified to reduce the cost. |
