Image forming apparatus having photosensitive member providing a belt with developer and cleaning member for cleaning the belt

An image-forming apparatus comprising:

• an endless belt configured to be circularly movable to convey a recording medium and having a surface extending in a first direction;
• a plurality of photosensitive members opposed to the surface to provide the recording medium conveyed by the endless belt with toner;
• a driving member configured to drive the endless belt so that the surface moves in the first direction during an image-forming period and moves in a second direction opposite to the first direction during a recovering period after the image-forming period;
• a recovering member that recovers, during the image-formation period, first residual toner remaining on the at least one of the plurality of photosensitve members after the toner has been provided on the recording medium, and provides, during the recovering period, the recovered first residual toner on the at least one of the plurality of photosensitive members to be provided on the surface;
• a cleaning member opposed to the surface upstream of the plurality of photosensitive members in the first direction to clean, during the recovering period, the recovered first residual toner provided on the surface;
• and
• a plurality of developing members corresponding to the plurality of photosensitive members, respectively, each developing member contacting the corresponding photosensitive member to provide toner thereon during the image-forming period, and separated from the corresponding photosensitive member during the recovering period.
