ABSTRACT:
A layered electrophotographic photoconductor is disclosed having a ground plane layer, a charge generating layer carried by the ground plane layer, and a charge transport layer carried by the charge generating layer. The polymeric binder material of the charge transport layer and the charge generation layer comprises an ordered copolyestercarbonate whose ester content is in the range of about 35 wt. % to about 70 wt. %, of which about 60 wt. % to about 70 wt. % is preferred, and of which about 70 wt. % is the most preferred. The charge generating molecule is a squarylium, and more specifically 2,4-bis-(4-dimethylamino-2-hydroxyphenyl) cyclobutene diylium-1,3-diolate (OHSQ), or an operative phthalocyanine compound, and preferably oxytitanium phthalocyanine. The charge transporting molecule is a hydrazone, and more specifically 4-diethylaminobenzaldehyde-1,1-diphenylhydrazone (DEH), or 4-diphenylaminobenzaldehyde-1,1-diphenylhydrazone (TPH).
