Electrophotographic apparatus
First Claim
1. An electrophotographic apparatus comprising:
- an electrophotographic photosensitive member which comprises a support, a charge generation layer formed on the support and containing a charge generating material, a charge transport layer formed on the charge generation layer and containing a charge transporting material, and a surface protective layer formed on the charge transport layer; and
an exposure device which irradiates a surface of the electrophotographic photosensitive member with an exposure beam based on image information so as to form an electrostatic latent image on the surface of the electrophotographic photosensitive member,wherein the surface protective layer comprises 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 μ
m or more to 1.5 μ
m or less, andwherein 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.
