    摘要: A method for producing an electrophotographic photosensitive member including: forming a photosensitive layer; and forming a protective layer, wherein the step of forming the photosensitive layer forms a photosensitive layer having an amount of residual solvent of a first solvent in the photosensitive layer of 0.05% to 2.50% and an amount of residual solvent of a second solvent in the photosensitive layer of 0.50% to 2.50%, and the step of forming the protective layer includes step (A) of forming a cured film and step (B) of forming the protective layer having wrinkle shapes, wherein, in step (A), the irradiated coating film is heated at a heating temperature lower than a boiling point of the first solvent and in step (B), the cured film is heated at a heating temperature higher than a boiling point of the first solvent.

    摘要: A process cartridge includes an electrophotographic photosensitive member, a charging device, and a developing device. The electrophotographic photosensitive member has a surface layer containing a polyarylate resin and a polycarbonate resin. The electrophotographic photosensitive member has an outer diameter of 23 mm or less and the developing device is configured to collect a residual toner left on the electrophotographic photosensitive member. A toner has a weight-average particle diameter (D4) of 7.1 μm or more and 10.0 μm or less, an average circularity of 0.95 or more, and an average aspect ratio of 0.90 or more.
