    摘要: 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.

    摘要: An imaging member is disclosed which includes a charge generating layer and a charge transport layer. The charge transport layer includes a first charge transport layer adjacent the charge generating layer and at least a second charge transport layer adjacent the first charge transport layer. Each charge transport layer includes a film forming polymer binder and a charge transport material dispersed therein. The first charge transport material has a composition which is the same or different than the second charge transport material and of a lower concentration. It may be selected from an aryl amine, aryl diamine, or combinations thereof. The combination has the effect of reducing charge deficient spots.
