Abstract

An electrophotographic recording material, composed of an electrically conductive substrate; a first layer provided on the electrically conductive substrate and composed of an amorphous selenium-tellurium alloy containing form 0.05 to 15 weight % tellurium; a second layer disposed on the first layer and composed of an amorphous selenium-tellurium alloy containing from 15 to 60 weight % tellurium; and a third layer provided on the second layer and composed of an amorphous alloy of selenium and from 0.05 to 5 weight % of one arsenic or tellurium. The electrophotographic recording material is particularly useful in an electrophotographic recording system which includes an infrared radiation means, such as an infrared solid state laser.
