Abstract
Abstract A polymer of the formula: wherein 0 = phenyl or phenylene b = 0, 1, 2 or 3 n = 3 or greater, and an imaging member (30) comprising a charge generation layer (12) comprising a layer (13) of photoconductive material and a contiguous charge transport layer (15) comprising a polymer resulting from the condensation of an aromatic diamine compound and an aromatic dihalo compound.
