ABSTRACT:
An improved enhancement layer operatively disposed between the top protective layer and the photoconductive layer of an electrophotographic device. The enhancement layer is specifically tailored from a semiconductor alloy material designed to substantially prevent charge carriers from being caught in deep midgap traps as said carriers move toward the surface of the electrophotographic device from the photoconductive layer thereof. A method of substantially improving charge fatigue and image flow characteristics through the use of such an improved enhancement layer is also disclosed.
