An electrophotographic photosensitive member is constituted by disposing a protective layer and a photosensitive layer on an electroconductive support in this order. The protective layer is characterized by containing an electroconductive particles, fluorine-containing resin particles and a binder resin. The photosensitive layer is suitable for providing an electrophotographic apparatus showing excellent electrophotographic characteristics such as a high photosensitivity and a low residual potential and also providing good image forming properties under any environmental condition, improved pause memory characteristics and a decreased transfer memory.
