<p>PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor that can suppress unevenness in density of halftone images after repeated image formation, and the occurrence of a change in density due to the history of the previous cycle.SOLUTION: There is provided an electrophotographic photoreceptor that includes: a conductive substrate 1; an undercoat layer 2 that is arranged on the conductive substrate and contains a binder resin and, as surface treatment particles in which the surface of metal oxide particles has been treated with a silane coupling agent having an amino group, first surface treatment particles having a BET specific surface area of 10 m/g or more and 15 m/g or less and second surface treatment particles having a BET specific surface area of 18 m/g or more and 30 m/g or less; and a photosensitive layer 3 that is arranged on the undercoat layer.</p> |
