Abstract

An electrophotographic photoreceptor includes a conductive substrate, an undercoat layer that is provided on the conductive substrate and contains an electron transport material and a binder resin, a charge generation layer that is provided on the undercoat layer, and a charge transport layer that is provided on the charge generation layer, in which, in the undercoat layer, a ratio (X1/X2) of a content X1 (% by mass) of the electron transport material in a region within 4% in a thickness direction of the undercoat layer from an interface between the undercoat layer and the charge generation layer to a content X2 (% by mass) of the electron transport material in a region exceeding 4% in the thickness direction of the undercoat layer from the interface between the undercoat layer and the charge generation layer is 0 or 78 or less.
