Abstract
Abstract Disclosed are improved photoresponsive imaging members comprised of chloroindium phthalocyanine photogenerating compositions. More specifically, there is disclosed a photoresponsive imaging member comprised of a supporting substrate, an adhesive layer, a chloroindium phthalocyanine photogenerating pigment in contact with the adhesive layer, and a hole transport layer comprised of an aryl amine dispersed in an inactive resinous binder. There is also disclosed photoresponsive imaging members comprised of a first photogenerating layer, and a second photogenerating layer, which imaging members are sensitive to light in the region of from about 400 to about 900 nanometers.
