PURPOSE:To remove exactly a toner and also to raise the durability of a blade by providing plural cleaning blades in the moving direction of a photosensitive body to clean the circumferential surface of the photosensitive body. CONSTITUTION:Two blade supporting members 5 are installed to the upper and lower parts in a housing 3, and a blade 8 of an elastic body is sandwiched to its tip of the member so as to be freely oscillatable by a sandwiching piece 7, and made to contact by pressing to the circumferential surface of a photosensitive body 1. The photosensitive body 1 rotates counterclockwise, a toner remaining on its circumferential surface is scraped by a lower blade 8b, and also scraped by an upper blade 8a, too. Accordingly, since the remaining toner is scraped by two stages, removed exactly, and pressure per piece of blade against the photosensitive body is reduced, therefore, not to produce a chattering and a flaw on the circumferential surface of the photosensitive body 1 and to raise the durability remarkably. |
