An electrophotographic photoreceptor is disclosed which is constituted by a conductive substrate, a barrier layer formed thereon, and a photoconductive layer, formed on the barrier layer, for generating photocarriers upon radiation of light. A portion of the barrier layer is formed by alternately stacking first thin films consisting of amorphous or microcrystalline silicon containing an element which controls a conductivity type and second thin films, these having a band gap wider than that of the first thin film. A multilayered structure made up of the first and second thin films has a superlattice structure.
