Abstract
A process for preparing an electrophotographic imaging member having a coating of photoconductive particles dispersed in a polymerizable film forming monomer, which when polymerized forms a charge generating layer.
Claims6
A process for preparing an electrophotographic imaging member comprising the steps of:
- a) providing a supporting substrate having a conductive layer and a charge blocking layer;
- b) coating said substrate with a film forming photoconductive dispersion comprising photoconductive particles made of benzimidazole perylene and a dispersion medium consisting essentially of a polymerizable film forming vinyl monomer;
- c) polymerizing said photoconductive film forming dispersion by autocatalysis to form a charge generating layer;
- and
- d) forming a charge transport layer on top of said charge generating layer.
