Abstract
An intermediate layer having fine hydrophobic silica particles is positioned between a substrate and a photosensitive layer. The fine hydrophobic silica particles preferably have a primary particle-averaged particle size of not more than 50 nm and desirably the surface of the fine hydrophobic silica particles is alkyl-silylated or treated with silicone.
Claims14
A photosensitive body for electrophotography, comprising:
- a conductive substrate;
- an intermediate layer formed on said conductive substrate, said intermediate layer being non-photosensitive and consisting essentially of fine particles of hydrophobic silica and a binder in which said fine particles of hydrophobic silica are dispersed;
- and
- a photosensitive layer formed on said intermediate layer.
