    摘要: Electrophotographic recording material composed of a layer of selenium, selenium alloys, or selenium compounds, with arsenic as a additive, disposed on a conductive carrier is given improved properties by forming the layer to have a total arsenic content of 1 to 20%, by weight, and a concentration gradient such that the arsenic concentration decreases from the exposed surface of the layer in the direction toward the carrier and has a concentration of at least 13% at the exposed surface of the layer.
