Abstract:
1. An electrophotographic photoreceptor comprising: a conductive substrate; a photosensitive layer including a charge-generating layer containing a charge-generating material and a charge-transporting layer containing a first charge-transporting material, the charge-transporting layer having a hole mobility of 5.0×10 an overcoat layer that is provided on the photosensitive layer and contains a cured material of at least one compound and at least one second charge-transporting material, the at least one compound being selected from a group consisting of guanamine compounds and melamine compounds, the at least one second charge-transporting material having at least one substituent selected from a group consisting of —OH, —OCH wherein the following relational expression (1) is satisfied wherein Ip(CGL) represents an ionization potential (eV) of the charge-generating material; Ip(CTL) represents an ionization potential (eV) of the first charge-transporting material; and Ip(OCL) represents an ionization potential (eV) of the at least one second charge-transporting material.
