An apparatus for cleaning an endless belt, on both side end portions of the inner peripheral surface of which a pair of belt-shaped side stoppers are provided, includes a blade pressed against the outer peripheral surface of the belt and a backup roller. At both side end surfaces of the roller, assistant support rollers are provided to support the both side stoppers to prevent the both side end portions of the belt from moving inward to separate from the blade by a pressure applied from the blade. An image forming apparatus having such a belt cleaning apparatus includes a plurality of image carrying bodies arranged side by side along the belt, a plurality of toner image developer for developing images on the carrying bodies by toner, and a plurality of transfer units for transferring the developed toner images on the image carrying bodies to a paper sheet transferred by the belt.
