ABSTRACT:
A charge generating layer for an electrophotographic imaging member is provided containing trigonal selenium and phthalocyanine photoconductive particles dispersed in a film forming polymer binder. The film forming polymer binder may be a styrene butadiene copolymer having a weight percent styrene to butadiene content of about 85:15 to about 95:5 and a glass transition temperature range of about 50.degree. C. to about 60.degree. C. A process for producing the homogeneous dispersion of photoconductive particles includes separately milling the trigonal selenium particles and the phthalocyanine particles to approprite particle sizes, and dispersing the separately milled particles in the film forming polymer binder.
