The toner layer restricting member includes an inclined portion formed in a lateral region outside of an image forming region to incline gradually away from a surface of a cleaning roller with increasing distance from an inner side of the lateral region. The toner receiving member includes a lower-level upper end portion provided in the lateral region outside of the image forming region, the lower-level upper end portion being located below a second contact region where the cleaning roller and the toner supply roller come into contact with each other. The inclined portion is disposed in a region overlapping the lower-level upper end portion.
