Patent number: 8265517Abstract: An image-forming apparatus includes an endless belt, a photosensitive member, a driving member, a recovering member, and a cleaning member. The endless belt has a surface extending in a first direction. The photosensitive member opposes the surface to provide the surface with toner. The driving member drives the belt so that the surface moves in the first direction during an image-forming period and moves in the opposite direction during a recovering period after the image-forming period. The recovering member recovers, during the image-formation period, residual toner remaining on the photosensitive member after the toner has been provided on the surface, and provides, during the recovering period, the recovered residual toner on the photosensitive member to be provided on the surface. The cleaning member opposes the surface upstream of the photosensitive member in the first direction to clean, during the recovering period, the recovered residual toner provided on the surface.Type: GrantFiled: June 17, 2009Date of Patent: September 11, 2012Assignee: Brother Kogyo Kabushiki KaishaInventors: Kensuke Miyahara, Shougo Sato, Susumu Sakuma
