摘要:
An electrophotographic recording material comprises a dual photoconductive layer applied to an electrically conductive substrate. The lower layer disposed on the substrate is made of an amorphous system of selenium and arsenic containing 18 to 37 percent by weight arsenic. The layer thereabove is made of As.sub.2-x Bi.sub.x Se.sub.3 or As.sub.2 Se.sub.3-y Te.sub.y. The recording material is highly sensitive in the visible spectral range as well as in the IR range and can therefore also be used for recordings with solid state laser diode radiation. In cyclic operation, the material exhibits only slight fatigue.
