Abstract
An electrophotographic photoreceptor includes an intermediate layer, a photosensitive layer, and a surface protective layer, deposited in this order on an electroconductive support. The surface protective layer includes a resin and a p-type semiconductor microparticle contained in the resin. The intermediate layer includes a resin and at least one metal oxide microparticle contained in the resin. The at least one metal oxide microparticle is selected from the group consisting of untreated tin oxide particles, tin oxide particles surface-treated with organic compounds, untreated anatase titanium oxide particles, anatase titanium oxide particles surface-treated with organic compounds, untreated rutile titanium oxide particles, and rutile titanium oxide particles surface-treated with organic compounds.
