    摘要: As the surface layers of an electrophotographic photosensitive member, a first surface layer which satisfies a condition that a center line average surface roughness (Ra) ranges from 50 Å to 5000 Å and a second surface layer comprising a non-single-crystal carbon containing at least fluorine are laminated in this order. Thus, the generation of a defective image such as the dimness of an image or an image smearing can be suppressed under an environment of high temperature and high humidity without providing any heater even when an electrophotographic apparatus is repeatedly employed. Further, even when a toner of small particle size and excellent in its fixing characteristic is used, a cleaning characteristic can be improved and the fusion of the toner can be suppressed. Still further, even in an electrophotographic process with a frictional force raised for improving the cleaning characteristic, the cleaning characteristic can be improved and the fusion of the toner can be suppressed.
