Abstract
A coating liquid for an undercoat layer of an electrophotographic photoreceptor which is formed by sequentially stacking the undercoat layer and a photosensitive layer on an electrically conductive support, wherein the coating liquid comprises titanium oxide microparticles and silicon nitride microparticles as an inorganic compound, a binder resin and an organic solvent.
Claims4
An electrophotographic photoreceptor comprising an undercoat layer and a photosensitive layer stacked on an electrically conductive support, wherein the undercoat layer comprises titanium oxide microparticles and silicon nitride microparticles as inorganic compounds and a binder resin, said silicon nitride microparticles being in an amount of 1.2 to 10% by weight relative to the titanium oxide microparticles.
