Abstract
There is provided an electrophotographic photoreceptor obtained by sequentially laminating at least a photosensitive layer and an outermost layer on a conductive support, wherein the outermost layer contains a polymerized and cured product of a composition containing a polymerizable monomer and a filler, and the filler includes a conductive first filler surface-treated with a surface treatment agent having a silicone chain in a side chain, and a second filler having a relative dielectric constant which is lower than that of the first filler and 5 or less.

An electrophotographic photoreceptor obtained by sequentially laminating at least a photosensitive layer and an outermost layer on a conductive support, wherein
- the outermost layer contains a polymerized and cured product of a composition containing a polymerizable monomer and a filler,
- the filler includes a conductive first filler surface-treated with a surface treatment agent having a silicone chain in a side chain, and a second filler having a relative dielectric constant which is lower than that of the first filler and 5 or less, and
- the surface treatment agent is bonded to the first filler by reacting a functional group of the surface treatment agent with the first filler, and the functional group is selected from the group consisting of a carboxylic acid group, a hydroxy group, —Rd-COOH wherein Rd represents a bivalent hydrocarbon group, an alkylsilyl group, a halogenated silyl group, and an alkoxysilyl group.
