Photoconductive imaging members

A photoconductive imaging member comprised in the following sequence of a supporting substrate, a first hydroxygallium phthalocyanine photogenerator layer which absorbs light of a wavelength of from about 550 to about 950 nanometers, a first charge transport layer, a barrier layer, to prevent diffusion of transport molecules from said first charge transport layer into the second photogenerator layer, a second photogenerator layer comprised of a mixture of bisbenzimidazo(2,1-a-1',2'-b)anthra(2,1,9-def:6,5,10-d'e'f')diisoquinoline -6,11-dione and bisbenzimidazo(2,1-a:2',1'-a)anthra(2,1,9-def:6,5,10-d'e'f')diisoquinoline -10,21-dione which absorbs light of a wavelength of from about 500 to about 800 nanometers, and thereover a second charge transport layer.
