A cleaning device for removing residual toner on a surface of an electrophotographic photosensitive member includes a cleaning blade for scraping residual toner off the surface of the photosensitive member, and a toner supply portion, disposed in an upper stream side of the cleaning blade as viewed in a moving direction of the surface of the photosensitive member, for causing toner to stick to the surface of the photosensitive member, the toner supply portion being switchable between a first mode of causing toner to stick to the surface of the photosensitive member to supply toner to the nip between the surface of the photosensitive member and the cleaning blade and a second mode of not causing toner to stick to the surface of the photosensitive member or of decreasing an amount of toner to be stuck to the surface of the photosensitive member, the second mode being selectable when a main switch of an image forming apparatus having the cleaning device mounted therein has become turned on.
