Abstract
The invention provides an electrophotographic photoreceptor having at least a conductive substrate and a photosensitive layer formed on the conductive substrate wherein the outermost surface layer of the photoreceptor is composed of a cured material containing at least one compound represented by the formula (I) and a surfactant that contains, in the molecule thereof, at least one structure selected from (A) a structure that is obtained by polymerizing an acrylic monomer having a fluorine atom, (B) a structure having a carbon-carbon double bond and a fluorine atom, (C) an alkyleneoxide structure, and (D) a structure having a carbon-carbon triple bond and a hydroxy group. In formula (I), Q is an organic group having a valency of n and having hole transportability, R is a hydrogen atom or an alkyl group, L is a divalent organic group, n is 1 or more, and j is 0 or 1.
