ABSTRACT:
The photoconductive element of the invention comprises an electrically conductive support and a photoconductive material capable of generating positive charge carriers when exposed to actinic radiation, the element having, situated between the support and the photoconductive material, an electrical barrier layer that restrains the injection of positive charge carriers from the conductive support, the barrier layer comprising a polyester ionomer. The method of the invention comprises coating on an electrically conductive support an aqueous dispersion of a polyester ionomer as a barrier layer, coating a charge generation layer over the barrier layer, and coating a p-type charge transport layer over the charge generation layer.
