Photoreceptors for use in electrophotographic copying devices are frequently formed on insulating substrates, and in such cases, establishing an electrical contact to the conductive layer beneath the photoconductive surface presents a practical problem. Such an electrical connection is required in order to establish ground potential, particularly when electrostatically charging the photosensitive layer, when developing it, and when transferring a developed image from it.
