Abstract

See full text

An electrophotographic photoreceptor includes: a conductive support; and a photosensitive layer which contains an electric charge generating material and an electric charge transport material, wherein a layer configuring a surface of the electrophotographic photoreceptor contains a resin binder, and conductive particles A and B dispersed in the resin binder, the conductive particles A have a single peak and volume resistance ρ1, the conductive particles B have a single peak and volume resistance ρ2, when a particle diameter of the conductive particles A is set to d1, and a particle diameter of the conductive particles B is set to d2, Expression (1) is satisfied, and when the volume resistance of the conductive particles A is set to ρ1, and the volume resistance of the conductive particles B is set to ρ2, Expression (2) is satisfied:
