Abstract
Abstract An electrophotographic light-sensitive material is disclosed. The material is comprised of a conductive layer containing cuprous iodide and a photoconductive layer. The photoconductive and electrophotographic characteristics are improved by forming a gelatin interlayer between the conductive layer and the photoconductive layer. The electrophotographic light-sensitive material can be used with either positive polarity or negative polarity.
