Abstract
In an image formation apparatus such as an electrophotographic printing apparatus, a cleaning device can effectively clean the peripheral surface of a photosensitive drum throughout the full length. The cleaning apparatus includes a fur brush 32 rotating while keeping contact with the entire periphery of a photosensitive drum 6. The cleaning characteristics of this fur brush 32 change between an outside portion R opposing gap roller contact portions at both end portions outside a print area of the photosensitive drum 6 and an inside portion inside this outside portion R.
