ABSTRACT:
An organic, positive-charging photoconductor for laser printers is disclosed. The photoconductor has a conductive substrate, a hydroxy-containing binder which forms a layer greater than or equal to about 1 micron thick on the substrate, a phthalocyanine pigment uniformly distributed throughout said binder, and a reactive stabilizer containing silicon, also uniformly distributed throughout said binder. The silicon-containing stabilizer reacts with the hydroxy group in the binder, the effect of which is to improve the electrical stability of the photoconductor in the severe laser printing electrophotographic environment, and to improve surface release characteristics of the photoconductor for more efficient toner image transfer.
