PURPOSE:To surely prevent the stick step of a cleaning blade with a simple constitution by adopting a means where a film or a thin plate is stuck to a specific surface of the cleaning blade. CONSTITUTION:The lower face of a cleaning blade 1 forms angles alpha and betato a tangent (l) passing the contact between a photosensitive drum 15 and the cleaning blade 1, and a film or thin plate 2 is stuck to the side of the smaller angle alpha of the lower face of the cleaning blade 1. Thus, the stick step of the cleaning blade 1 is surely prevented in case of the trail system as well as the counter system, and the fear of disturbance of images is prevented because the photosensitive drum 15 is not oscillated. |
