Abstract

An electrophotographic recording material including a dual photoconductive layer containing selenium applied to an electrically conductive substrate. The dual photoconductive layer includes a layer of arsenic selenide applied to the substrate, and a layer of an arsenic-selenium-tellurium compound superposed on the arsenic selenide layer. The arsenic-selenium-tellurium compound has the formula As.sub.2 Se.sub.3-x Te.sub.x, where 0<X<3.
