Disclosed is the use of a carbon black dispersed polymer film as an adhesive electrode for fabricating alloy photoreceptors on a plain Mylar substrate (commercially available from E. I. du Pont deNemours & Company). In one embodiment there was prepared a flexible photoreceptor, which is comprised of an organic substrate such as Mylar overcoated with an adhesive flexible electrode of carbon black or graphite dispersed in a polyester material, and this layer is in turn overcoated with a photoconductor such as selenium. The dispersed carbon black film functions as a conductive medium with the polymer performing the function of an adhesive between the substrate and the photoconductor. The dispersed carbon film also functions as an electron-blockingcontact.
