Abstract
In an organic photoreceptor that has a protective layer formed on an organic photosensitive layer, the protective layer contains; a cured resin constituent obtained by polymerizing a polymerizable compound in the presence of a radical scavenger represented by the general formula (2); metal oxide microparticles; and a compound represented by the general formula (1) as a charge transport substance, and the relational expression (1): 80/A≦B≦160/A and the relational expression (2): 12≦A≦25 are satisfied when the volume ratio (volume %) of the metal oxide microparticles in the protective layer and the volume ratio (volume %) of the compound represented by the general formula (1) in the protective layer are respectively denoted by A and B.
