Abstract
An electrophotographic photoreceptor includes a conductive substrate, an undercoat layer on the conductive substrate, a charge generation layer on the undercoat layer, a charge transport layer on the charge generation layer, and an inorganic protection layer on the charge transport layer, in which the charge transport layer contains a binder resin and a charge transport material, and, when impedance of the charge transport layer is measured, a ratio (C/C) of an electrostatic capacitance Cat 1 Hz to an electrostatic capacitance Cat 10 Hz is 1.1 or less.
