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.
Claims8
In an electrophotographic recording material including a dual photoconductive layer containing selenium applied to an electrically conductive substrate, the improvement wherein the recording material contains only the substrate and the dual photoconductive layer, and the dual photoconductive layer consists of a layer of amorphous arsenic selenide as a charge transporting layer disposed on said substrate, and a layer of a compound of arsenic, selenium, and tellurium of the formula As.sub.2 Se.sub.3-x Te.sub.x, where 0<.times.<3, as a charge generating layer, superposed on said layer of arsenic selenide.
