Light receiving member having a multilayered light receiving layer
composed of a lower layer made of aluminum-containing inorganic
material and an upper layer made of a non-single-crystal silicon
material
摘要:
A light receiving member for electrophotography made up of an aluminum support and a multilayered light receiving layer exhibiting photoconductivity formed on the aluminum support, wherein the multilayered light receiving layer consists of a lower layer in contact with the support and an upper layer, the lower layer being made of an inorganic material containing at least aluminum atom (Al), silicon atoms (Si) and hydrogen atoms (H), and having portion in which the aluminum atoms (Al), silicon atoms (Si), and hydrogen atoms (H) are unevenly distributed across the layer thickness, the upper layer being made of a non-single-crystal material composed of silicon atoms (Si) as the matrix and at least either of hydrogen atoms (H) or halogen atoms (X) and containing at least one of carbon atoms, nitrogen atoms (N) and oxygen atoms (O) in the layer region in adjacent with the lower layer. The light receiving member for electrophotography can overcome all of the foregoing problems and exhibits extremely excellent electrical property, optical property, photoconductivity, durability, image property and circumstantial property of use.
