Abstract
An electrophotographic photoreceptor includes a conductive substrate satisfying a condition (A); an undercoat layer satisfying conditions (B) and (C), disposed on the conductive substrate, and containing metal oxide particles; and a photosensitive layer disposed on the undercoat layer: condition (A): in the case where depressions existing in the surface of the conductive substrate are observed with a laser microscope, the width of the largest depression is 400 μm or less, and the depth of the depression is 15 μm or less; condition (B): in the case where the undercoat layer is subjected to a Cole-Cole plot analysis, an angular frequency ωmax at which a complex impedance component is maximum is from 2.0 rad to 25.0 rad; and condition (C): volume resistivity obtained from the Cole-Cole plot analysis of the undercoat layer is from 7.0×10Ω to 1.0×10Ω.
