Abstract
A photoconductive member comprising a support and a silicon amorphous layer, and the silicon amorphous layer has a first layer region containing at least one of oxygen, nitrogen and carbon and a second layer region containing an element of Group III. The first layer exists internally within the amorphous layer below its surface.
Claims41
A photoconductive member comprising a support for a photoconductive member and an amorphous layer having photoconductivity constituted of an amorphous material comprising silicon atoms as a matrix, characterized in that said amorphous layer has a first layer region containing at least one kind of atoms selected from the group consisting of oxygen atoms, nitrogen atoms and carbon atoms as constituent atoms and a second layer region containing atoms of an element belonging to the group III of the periodic table as constituent atoms, said first layer region existing internally within said amorphous layer below the surface of said amorphous layer wherein the amorphous layer contains at least one of hydrogen atoms and halogen atoms as constituent atoms.
A photoconductive member comprising a support for a photoconductive member and an amorphous layer having photoconductivity constituted of an amorphous material comprising silicon atoms as a matrix, characterized in that said amorphous layer has, in the order from the support side, a first layer region containing at least one kind of atoms selected from the group consisting of oxygen atoms, nitrogen atoms and carbon atoms as constituent atoms and an upper layer region provided in direct contact with said first layer region and containing no atom selected in said first layer region, and a second layer region containing atoms of an element belonging to the group III of the periodic table as constituent atoms is provided such that at least a part of the second layer region overlaps at least one of said first layer region and said upper layer region wherein the amorphous layer contains at least one of hydrogen atoms and halogen atoms as constituent atoms.
