Abstract:
An electrophotographic apparatus is provided including an electrophotographic photosensitive member which includes a surface protective layer; and an exposure device which irradiates a surface of the electrophotographic photosensitive member with an exposure beam so as to form an electrostatic latent image on the surface of the electrophotographic photosensitive member, wherein the surface protective layer includes a material having no structure to provide charge transporting performance and has a plurality of through holes penetrating from the side of the front surface of the surface protective layer to the side of the charge transport layer, and the thickness of the surface protective layer is from 0.1 μm or more to 1.5 μm or less, and wherein when the surface of the electrophotographic photosensitive member is irradiated with the exposure beam, two or more of the through holes are included in an exposure beam spot.
