Abstract

An electrophotographic apparatus and a process cartridge include an electrophotographic photosensitive member; a developing unit; and a cleaning unit, wherein depressed portions separated from each other and satisfying conditions below are formed in the surface of the electrophotographic photosensitive member at a density of 10 or more per unit area of 1 cm²: a depth of the depressed portions is defined as Rdv[μm], a minor-axis diameter of the depressed portions is defined as Lpc[μm], a major-axis diameter of the depressed portions is defined as Rpc[μm], and an angle formed between a direction of a major-axis of each of the depressed portions and a direction of movement of the surface of the electrophotographic photosensitive member is defined as θ[°].
