Abstract
In a method for producing an electrophotographic recording material composed of a dual layer of amorphous and crystallized selenium applied to an electrically conductive substrate, tellurium is vapor-deposited in a vacuum onto the surface of the conductive substrate to a layer thickness of about 0.5 to about 5 nanometers to form a tellurium layer, and selenium is vapor-deposited onto the tellurium layer to a layer thickness of about 20 to about 100 microns to form the dual layer of amorphous and crystallized selenium.
