Abstract
An image forming apparatus includes a photoreceptor that includes a conductive substrate, a photosensitive layer, and an inorganic surface layer arranged in that order, the inorganic surface layer containing a group 13 element and oxygen; a charging unit; an electrostatic image-forming unit; a developing unit; a transfer unit; a cleaning unit that performs cleaning by causing the cleaning blade to contact the surface of the photoreceptor; and a supply unit that supplies a fatty acid metal salt to a position where the cleaning blade in the cleaning unit contacts the photoreceptor. When the fatty acid metal salt is supplied, a portion of the surface of the photoreceptor downstream of the supply unit and upstream of the cleaning unit in a rotating direction of the photoreceptor is covered with a metal derived from the fatty acid metal salt at a coverage of about 40% or more.
