Abstract
An electrophotographic photoreceptor that can sufficiently prevent occurrence of filming, whereby defects on an image can be sufficiently prevented, and an electrophotographic process cartridge and an electrophotographic apparatus using the electrophotographic photoreceptor are to be provided. The electrophotographic photoreceptor contains an electroconductive substrate having provided thereon a photosensitive layer, and an outermost layer of the photosensitive layer has a dynamic hardness of about from 13.0×10to 100.0×10N/m. According to the invention, occurrence of flaws on the surface of the photoreceptor can be sufficiently prevented, and cracking of a member made in contact with the photoreceptor can also be sufficiently prevented. Therefore, occurrence of filming is sufficiently prevented, and occurrence of defects on an image is also sufficiently prevented.
