Abstract

An electrophotographic imaging member containing a supporting substrate having an electrically conductive surface comprising charge injecting material, a charge blocking layer including a water insoluble high molecular weight unmodified hydroxy methacrylate polymer and at least one photoconductive layer, the charge blocking layer having a surface resistivity greater than about 10.sup.10 ohm/sq. This imaging member may be employed in an electrostatographic imaging process.
