ABSTRACT:
The recording material comprises a metallic base, for example, of aluminum, a twenty to sixty .mu.m thick layer of selenium with a content of tellurium ranging between 5 and 30 percent by wt. and a layer of selenium having a thickness ranging between 0.5 and 3 .mu.m arranged thereon containing 0.5 to 5 percent by wt. of arsenic. Instead of the layer of selenium containing arsenic, there may also be provided a layer of arsenic-triselenside. Preferably, the content of tellurium in the selenium layer containing tellurium, increases either step-by-step or continuously from the metallic base up to the layer of selenium containing arsenic. The electrophotographic recording material has a sensitivity within the region from 600 to 850 nanometers, the surface is stabilized against corona effects, and the material has a good residual potential behavior.
