Abstract (en)

[origin: US4652507A] Disclosed is an electrophotographic recording material comprising a photoconductive double layer disposed on an electrically conductive support, which double layer comprises a charge carrier-generating layer and a charge transport layer. The interface region of the charge carrier-generating and charge transport layers defines a mixing zone into which one or more of the constituents of the separate layers have diffused. A process for producing the electrophotographic recording material is also disclosed.
