PURPOSE:To enable the drastic reduction in size, weight and cost by adding an electrifying function and destaticizing function to a cleaning blade. CONSTITUTION:The cleaning blade 6b is formed by dispersing metal, such as aluminum oxide, and carbon into polyurethane so as to have a prescribed resistance value. The front end of the blade comes into contact with the surface of a photosensitive body 8 and the part continuous with this front end has an air gap 10b with the surface of the photosensitive body past the front end. The blade can make destaticization and electrification when the voltage superposed with AC 11 on DC 12 is impressed to the blade. The blade is provided with only the electrifying function by impressing the DC voltage alone thereto and is provided with only the destaticizing function by impressing the AC voltage alone thereto. |
