PURPOSE:To prevent the cleaning defect by the turning over, edge chipping, etc., of a cleaning blade without degrading electrophotographic characteristics by mechanically polishing the surface by using spherical shot or abrasive particles. CONSTITUTION:The surface is mechanically polished by using the spherical shot or abrasive particles. The shot collides against the surface of the electrophotographic sensitive body and bounces back without being captured by the surface if a sandblasting method is executed by using the shot and, therefore, the embedment of the shot arises only when the shot collides against the surface of the electrophotographic sensitive body as the external force to further embed the shot at the moment when the shot exists on the surface; in addition, the probability thereof is extremely low and, therefore, the embedment of the shot is substantially prevented. The turning over and edge chipping of the cleaning blade by the friction on the surface of the photosensitive body are prevented in this way and the excellent cleanability and images are obtd. without degrading the electrophotographic characteristics at all. |
