1. An electrophotographic photoreceptor comprising:
a conductive substrate; a photosensitive layer provided on or above the conductive substrate; and a protective layer that constitutes an outermost surface layer on the photosensitive layer and is made of a cured film obtained by curing a composition comprising a compound represented by the following Formula (M1) and a charge transporting material having a chain polymerizable functional group represented by the following Formula (I): wherein, in Formula (M1), X101 and X102 each independently represent a hydrogen atom, a halogen atom, an alkyl group having 1 to 15 carbon atoms, an alkoxy group having 1 to 15 carbon atoms, a cyano group, a phenoxy group, an aryl group having 6 to 30 carbon atoms, —Y101-X103 (wherein Y101 represents an azo group or a siloxy group; X103 represents an alkyl group having 1 to 15 carbon atoms, an alkoxy group having 1 to 15 carbon atoms, a cyano group, a phenoxy group, or an aryl group having 6 to 30 carbon atoms), or a substituent composed of any of these groups; R101 and R103 each independently represent a hydroxyl group or an alkoxy group having 1 to 15 carbon atoms; m11 and m13 each independently represent an integer of 0 or 1; R102 and R104 each independently represent an alkyl group having 1 to 15 carbon atoms; and m12 and m14 each independently represent an integer of 0, 1, 2, or 3; wherein, in Formula (I), F represents a hole-transporting organic group having an n valence; R represents a hydrogen atom or an alkyl group; L represents a divalent organic group; n represents an integer of 2 or more; and j represents 0 or 1; and wherein
a content of the compound represented by the Formula (M1) is from 0.1% to 5% by weight with respect to a weight of the composition for obtaining the cured film of the outermost surface layer, anda content of the charge transporting material having a chain polymerizable functional group represented by the Formula (I) is 40% by weight or more with respect to the weight of the composition for obtaining the cured film of the outermost surface layer.
