    摘要: A photosensitive member of the present invention comprises an electrically conductive substrate, a photoconductive layer and an overcoat layer.The photoconductive layer comprises selenium-arsenic alloy layer, or selenium layer and selenium-tellurium layer formed in this order. The overcoat layer comprises amorphous carbon containing hydrogen atoms, halogen atoms and at least one element selected from the group consisting of chalcogen, oxygen, nitrogen and elements in Group III and IV of the periodic table.The photosensitive member of this construction is harmless and excellent in electrophotographic characteristics inclusive of durability and surface hardness.
