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 polycarbonate resin having a weight average molecular weight ranging from about 25,000 to about 45,000 as an adhesive in the bonding layer on the electroconductive support and as a binder in the charge transporting layer forming a homogeneous phase to provide a receptive and retentive base layer for the charge-generating layer.
