Abstract
Disclosed herein is a photoreceptor for electrophotography having an over coating layer formed on a substrate and prepared by applying a composition containing silica particles, an organic compound chemically bonded thereto and a photo polymerization initiator and by curing said composition; said organic compound having an polymerizable unsaturated group, a group designated by Formula (1) or a group designated by Formula (2), and said silica particles and said organic compound being bonded with each other through a silyloxy group. The photoreceptor for electrophotography has not only excellent durabilities and an excellent resistance to printing but also excellent electrophoto characteristics such as sensitivity and a residual potential. ##STR1## (wherein --X-- is selected from --NH--, --O-- and --S--, --Y-- is an oxygen atom or a sulfur atom, and when --X-- is --O--, Y is said sulfur atom).
