ELECTROPHOTOGRAPHIC SENSITIVE BODY

摘要

PURPOSE:To reduce the dark decay of electrostatic charge potential by interposing an intermediate layer between an electrically conductive substrate and a photoconductive layer of amorphous silicon and using a dried and hardened substance of a soln. contg. at least one kind of org. aluminum compound as the material of the intermediate layer. CONSTITUTION:A photoconductive layer is made of an N type semiconductor contg. amorphous silicon contg. H as the principal component and P as an impurity and further contains at least one among C, N and O. An intermediate layer is made of a dried and hardened substance of a soln. contg. at least one kind of org. aluminum compound. The compound used may be trisacetylacetonatoaluminum. Such atoms are preferably contained because they are effective in increasing the dark resistance, photosensitivity and electrostatic chargeability (electrostatic charge potential per unit film thickness) of a photosensitive layer.
