PURPOSE:To prevent damage, abrasion and deformation of a photosensitive drum, by forming a cleaning blade of the photosensitive drum by a rubber-like elastic member having a triangular section. CONSTITUTION:A section shape of a rubber-like elastic member 11 for constituting a cleaning blade 10 which is made to press-contact with a photosensitive drum 1 is made almost triangular, and also its triangle is constituted on the plane side of an elastic plate body 12. To the elastic member 12 such as a phosphor bronze plate, a stainless steel plate, etc., an elastic member 11 such as urethane rubber, silicon rubber, natural rubber, etc. is formed as one body or is made to adhere. To the photosensitive drum, an edge line part 13 is made to abut. In this way, damage, abrasion and deformation of the photosensitive drum 1 are prevented. |
