摘要：
An electrophotographic photosensitive member has a surface layer that contains a polymer produced by the polymerization of a charge transporting substance having two or more methacryloyloxy groups per molecule. The surface layer contains a quinone derivative at a concentration of 5 ppm or more and 1500 ppm or less of the total mass of the polymer. The quinone derivative is a compound represented by the following formula (1) or a compound represented by the following formula (2) or both.
