Electrophotographic photoreceptor, process cartridge, and image forming apparatus

An electrophotographic photoreceptor comprising:

• a conductive substrate;
• a photosensitive layer provided on the conductive substrate;
• and
• an outermost surface layer provided on the photosensitive layer, wherein:
• the outermost surface layer comprises a polymerized product or a crosslinked product of a composition including:
• at least one reactive compound selected from compounds represented by formula (II), and
• a non-reactive charge transporting material;
• a content of the non-reactive charge transporting material in the composition is from 5% by weight to 40% by weight based on the weight of the outermost surface layer;
• and
• a content of the unreacted reactive compound in the outermost surface layer after formation of the outermost surface layer is 3% by weight or less based on the weight of the outermost surface layer,
• wherein in formula (II), F represents a charge transporting skeleton;
• L′ represents an (n+1)-valent linking group including two or more selected from the group consisting of a trivalent or tetravalent group derived from an alkane or an alkene, an alkylene group, an alkenylene group, —C(═O)—, —N(R)—, —S—, and —O—;
• R represents a hydrogen atom, an alkyl group, an aryl group, or an aralkyl group;
• m′ represents an integer of 1 to 6;
• and n represents an integer of 2 to 3.
