Interfacial barrier layers are typically employed in electro-photographic photoreceptors to reduce charge leakage in the absence of activating radiation (commonly referred to as "dark discharge"). Various interface systems may be used in such photoreceptors. These systems include: mixtures of phenoxy and polyurethane resins; mixtures of polycarbonate and chloro-prene resins; mixtures of polycarbonate and polyurethane resins; mixtures of epoxy and polyurethane resins; mixtures of polyester and polyurethane resins; mixtures of polycarbonate resins with terpolymers of acrylonitrile-butadiene-styrene; polyurethane resins; mixtures of epoxy and chioroprene resins; mixtures of epoxy and poly(butadiene/acrylonitrile) resins; mixtures of polyurethane and polyphenylene oxide resins; and mixtures of phenoxy and chloroprene resins. These interface systems are particularly well suited for use in endless flexible belt photoreceptors because of the adhesive and electrical properties of the materials.
