Abstract
An electrophotographic photoreceptor includes a conductive substrate, an undercoat layer that is provided on the conductive substrate, and a photosensitive layer provided on the undercoat layer, in which the undercoat layer contains a binder resin and an electron transport material having a crystal density of 1.62 g/cm3 or greater, and a full width at half maximum (FWHM) of a maximum intensity peak in an X-ray diffraction spectrum measured in a thickness direction is 5.0 or less.
