摘要:
The present invention provides an electrophotographic photoconductor capable of reducing latent electrostatic image stability defects caused by adhesion/adsorption of an electric discharge product formed by a charger in an image forming process, degradation of charge transportability and cleaning defects caused when removing a residual toner. The electrophotographic photoconductor has a conductive substrate, and a photosensitive layer which contains at least a binder, a charge generating material and a charge transporting material and is formed on the substrate, wherein the photosensitive layer contains an injection material composed of at least any one of one wax selected from paraffin waxes, Fisher-Tropsh waxes, polyolefin waxes and a polyorganosiloxane compound in an area from the surface of the photosensitive layer to 50% of the thickness thereof in the thickness direction of the electrophotographic photoconductor, and the content of the injection material is 3% by mass or more to the content of the binder.
