Abstract
An electrophotographic photoreceptor includes a conductive substrate, an undercoat layer that is provided on the conductive substrate, a charge generation layer that is provided on the undercoat layer, a charge transport layer that is provided on the charge generation layer, and a protective layer that is provided on the charge transport layer and has volume resistivity of 2×10Ω·m to 4×10Ω·m, and the work functions and electron affinities of the undercoat layer and the charge generation layer satisfy the following Expression (1): 0.4 eV≦(Efuc−Eauc)−(Efcg−Eacg)≦0.6 eV (where Efuc represents the work function of the undercoat layer, Eauc represents the electron affinity of the undercoat layer, Efcg represents the work function of the charge generation layer, and Eacg represents the electron affinity of the charge generation layer).
