Abstract: A photoconductor for electrophotography includes a base member; an anodic oxide coating provided on the base member and having a film thickness of 2 to 10 μm; an interlayer provided on the anodic oxide coating and containing a vinyl chloride-vinyl acetate copolymer resin and having a film thickness of 0.02 to 0.3 μm; and a photosensitive layer including a charge transport layer formed on the interlayer and containing a charge transport material and a first resin binder, and a charge generation layer laminated on the charge transport layer and containing a charge generation material, a hole transport material, a first electron transport material that is a naphthalenetetracarboxylic diimide compound, a second electron transport material that is an azoquinone compound, a diphenoquinone compound, or a stilbenequinone compound and that has a mobility of 17×10−8 cm2/V·s or more, and a second resin binder.
