PURPOSE:To uniformize the wear of a cleaning blade and prevent chattering at both end sides by making the cleaning blade longer in free length at both end sides than at the center side. CONSTITUTION:The both-end-side free length l2 of the cleaning blade 11 which scrapes untransferred toner remaining on the surface of a photosensitive body after a transfer process is made longer than the free length l1 at the center part side. The cleaning blade 11 and a blade holding member 13 are formed longer than the effective development width L1 on the photosensitive body and a cut 13a is formed at tip parts of both end sides of the blade holding member 13. |
