An image forming apparatus includes a rotatable image bearing drum; a toner image transfer device; a cleaning blade for cleaning the drum after transfer of the image; a rotatable furbrush provided downstream of the transfer device and upstream of the blade, the furbrush being rotatable counterdirectionally with respect to a peripheral movement of the drum; an executing portion for executing a first mode for forming an image on the transfer material on the basis of a signal inputted to the apparatus and a second mode for supplying a band of the toner to the blade; and a controller for controlling a peripheral speed difference between the drum and the furbrush, wherein the difference when the band of the toner passes the furbrush in the second mode is smaller than that when the toner on the drum after the image transfer passes the furbrush in the first mode.
