A photoreceptor including an electroconductive substrate; and a photosensitive layer overlying the electroconductive substrate, wherein the uppermost surface layer of the photosensitive layer has a three-dimensional cross-linked product formed by polymerization reaction of a charge transport compound A represented by the following Chemical Structure 1 and a charge transport compound B having three or more [tetrahydro-2H-pyran-2-yl)oxy]methyl groups linked with aromatic rings in which part of the [tetrahydro-2H-pyran-2-yl)oxy]methyl groups is severed and detached. In the Chemical Structure 1, Ar1 represents an aromatic hydrocarbon group having 6 to 20 carbon atoms that may have an alkyl group having one to four carbon atoms as a substitution group.
