Electrophotographic photoreceptor, process cartridge and image forming apparatus

An electrophotographic photoreceptor comprising:

• a conductive substrate;
• a photosensitive layer formed on the conductive substrate;
• and
• an outermost surface layer that is a layer made of a cured material of a composition including at least one compound represented by the following formula (I) and at least one compound having charge transportability and an azo group:
• wherein in formula (I), F represents an n-valent organic group having a hole transporting property, R represents a hydrogen atom or an alkyl group, L represents a divalent organic group, n represents an integer of 1 or more, and j represents 0 or 1,
• wherein the compound that has charge transportability and an azo group is a compound represented by the following formula (A):
• wherein in formula (A), Ar11 and Ar12 each independently represent a substituted or unsubstituted aryl group;
• X1 represents a divalent hydrocarbon group having an aromatic cyclic structure or a divalent heteroatom-containing hydrocarbon group having an aromatic cyclic structure;
• X2 and X3 each independently represent a substituted or unsubstituted arylene group;
• L1 and L2 each independently represent a divalent hydrocarbon group that may contain a branched or cyclic structure or a divalent heteroatom-containing hydrocarbon group that may contain a branched or cyclic structure;
• m1 and m3 each independently represent 0 or 1;
• m2 represents a number of 1 or more;
• and R′ represents a monovalent hydrocarbon group or a monovalent heteroatom-containing hydrocarbon group.
