High sensitivity visible and infrared photoreceptor

摘要

An electrophotographic imaging member including a charge generating layer containing a dispersed oxytitanium phthalocyanine polymorph and a charge transport layer containing a film forming charge transporting polymer including charge transporting moieties in the backbone of the film forming charge transporting polymer, for example, polysilylenes and polyarylamine derivative. The charge transporting polymers may optionally be used as a binder in the charge generating layer. The imaging member may be employed in an electrophotographic imaging process, particularly in high sensitivity infrared photoreceptors which are compatible with liquid ink development processes.
