Abstract: 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 D×S≧0.06 and D≦200 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.
