An electrophotographic apparatus comprises a photosensitive member, exposing means, and cleaning means for cleaning a residual developer from the photosensitive member, which comprises a cleaning brush brought into contact with the photosensitive member. In this case, a brush density of the cleaning brush is D (number/mm2), and an area of a pixel of an electrostatic image is S (mm2/dot), and DS0.06 and D200 are satisfied. Thus, an image forming apparatus is provided, in which cleaning stability is improved by uniformly scraping off and dispersing the transfer residual developer from the photosensitive member.
