An image forming apparatus (1) includes an image carrier (7), a rotat ing brush (33), a collecting roller (35), a cleaning blade (37), a sealing member (41) and a side sealing member (43). The sealing member (41) has an extension part (41a) extending outside from each end of the collecting roller (35) in an axial direction. The sealing member (41) comes into contact with the collecting roller (35) between a contact area (C1) between the rotating brush (33) and the collecting roller (35) and the cleaning blade (37) and then prevents backflow of the residue. The side sealingmember (43) lifts the extension part (41a) toward the collecting roller (35) on an outside at a predetermined interval from a position corresponding to each side edge of a maximum-width sheet passing region on the image carrier (7). |
