<p>PROBLEM TO BE SOLVED: To provide an electrophotographic photoreceptor and an image formation apparatus which suppress density unevenness caused by optical fatigue, and have excellent potential stability in repeated uses and a high film strength for a long life.SOLUTION: The electrophotographic photoreceptor contains, in an outermost surface layer, inorganic particles subjected to surface treatment using Q-D [Q represents a group including carboxyl group, phosphate group, cyano carboxyl group, vinyl group, methacryl group, or silyl group. D represents a group derived from a compound of the formula (2)]. [In the formula (2), n is 1 or 2; Rrepresents monovalent aromatic group, alkyl group or heterocyclic group, or may be coupled with each other to form a ring structure; Rrepresents monovalent aromatic group or alkyl group; Rrepresents monovalent aromatic group, alkyl group or heterocyclic group; and Ar represents divalent aromatic group.]</p> |
