Abstract
A negative-charge type electrophotographic photoreceptor includes a conductive substrate; an undercoat layer which includes a binder resin and metal oxide particles and in which the work function is from 4.0 eV to 4.7 eV; a charge generation layer in which a difference between the work functions of the charge generation layer and the undercoat layer is from −4 eV to 0 eV; and a charge transport layer which is provided on the charge generation layer.
