ABSTRACT:
A durable photoreceptor having improved flexibility comprising a metal- or metal-coated flexible substrate and an inorganic photoconductor layer in charge blocking contact, the photoreceptor being obtained by initially bombarding the metal substrate, as an electrode, with both negative and positive ions of a non-metallic gas of low ionization potential under AC glow discharge in the presence of oxygen; and exposing the resulting oxidized substrate to a vapor cloud of inorganic ambipolar photoconductive material consisting essentially of positively and negatively charged and uncharged photoconductive material in a low frequency AC electrical field, utilizing the substrate as one electrode, a source of said vapor cloud of photoconductive material or adjacent structure as the other electrode, the latter functional step being effected in combination with at least part of the initial bombardment step.
