1. An organic photoreceptor comprising:
a conductive support; an organic photosensitive layer formed on the conductive support; and a protective layer formed on the organic photosensitive layer, wherein the protective layer contains: a cured resin constituent obtained by polymerizing a polymerizable compound in the presence of a radical scavenger represented by the following general formula (2); metal oxide microparticles; and a compound represented by the following general formula (1) as a charge transport substance, the polymerizable compound has two or more acryloyl groups (CH2═CHCO—) or methacryloyl groups (CH2═CCH3CO—), and the following relational expression (1) and the following relational expression (2) 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,
80/A≦B≦160/A Relational Expression (1):12≦A≦25 Relational Expression (2): in the general formula (1), R1, R2, R3, and R4 each represents a hydrogen atom, an alkyl group having 1 to 7 carbon atoms, and an alkoxy group having 1 to 7 carbon atoms, k, l, and n each represents an integer of 1 to 5, and m represents an integer of 1 to 4, provided that when k, l, n, or m is 2 or more, multiple R1, R2, R3 and R4 may be identical to each other, or different from each other in the general formula (2), R5 and R6 each represents an alkyl group having 1 to 6 carbon atoms, and R7 represents a hydrogen atom or a methyl group. |
