<p>PROBLEM TO BE SOLVED: To provide an organic photoreceptor having appropriate flexibility that exhibits stress relaxation, while maintaining high hardness and a high elastic modulus.SOLUTION: The organic photoreceptor includes a photosensitive layer on a conductive support and a protective layer on an upper layer of the photosensitive layer, in which the protective layer comprises a cured composition formed by allowing a polyfunctional acrylic polymerizable oligomer having at least a urethane bond to react and cure with a polyfunctional curable compound having a spherical dendrimer structure. The polyfunctional acrylic polymerizable oligomer includes at least one of a radical polymerizable (meth)acryloyl group and a vinyl group as a polymerizable functional group, is soluble with an alcohol-based solvent, and has a weight average molecular weight of 1,000 or more.</p> |
