ABSTRACT:
An image-forming method suitable particularly for copying using image exposure wavelengths of 700 to 850 nm such as are experienced with semiconductor laser beam printers. Useful photosensitive members include photoconductive layer prepared from a dispersion of a photoconductive material including at least cadmium sulfide in a resin binder. The photosensitive member is sequentially subjected to a plurality of prehysteresis operations, each comprising electrostatically charging the member and uniformly exposing the same to light until the photosensitivity of the photosensitive member has been substantially stabilized.
