ABSTRACT:
Organic photoconductive elements with a charge generating layer and a charge transport layer carried on an electroconductive support are disclosed. The invention involves the combined use of a mixture of a polyester having a Tg (glass transition temperature) larger than about 60.degree. C. with a polyester having a Tg smaller than about 30.degree. C. in the adhesive bonding layer on the electroconductive support and in the charge transporting layer to provide a receptive and retentive base layer for the charge-generating layer.
