Abstract
In a process for producing an electrophotographic recording material composed of a double layer of amorphous and crystallized selenium on an electrically conductive carrier, a layer of tellurium having a thickness of 10 to 500 nm is applied onto the surface of the carrier, and selenium is then vapor-deposited onto the tellurium layer to a thickness of 20 to 100.mu. to form the double layer.
