Photosensitive member comprising charge generating layer and charge transporting layer

Claim 1

A photosensitive member comprising: an electrically conductive substrate; a charge generating layer comprising amorphous silicon as a mtrix containing germanium atoms in an amount of up to about 30 atomic % based on the combined amount of silicon atoms and germanium atoms and at least one of hydrogen and halogen atoms in an amount of about 10 to about 35 atomic % based on the combined amount of silicon atoms and hydrogen atoms or of silicon atoms and halogen atoms, said charge generating layer having a thickness of about 0.1 to about 5 microns; and a charge transporting layer comprising amorphous carbon containing hydrogen in an amount of about 30 to about 60 atomic % based on the combined amount of hydrogen atoms and carbon atoms, said charge transporting layer having a thickness of about 5 to about 50 microns and containing at least one of oxygen atoms in an amount of about 0.01 to about 7.0 atomic % and nitrogn atoms in an amount of about 0.01 to about 5.0 atomic % based on all the constituent atoms therein.
