Electrophotographic photoreceptor, electrophotographic photoreceptor cartridge, and image forming apparatus

An electrophotographic photoreceptor comprising:

• a conductive support;
• and
• a photosensitive layer on the conductive support,
• wherein the photosensitive layer contains a charge transport substance, a binder resin, and a compound which has a molecular weight of equal to or less than 350, and is represented by General Formula (1):
• (in Formula (1), Ar1 and Ar2 each independently represent at least one group selected from the group consisting of a hydrogen atom, an alkyl group, a phenyl group which may have a substituent, a naphthyl group which may have a substituent, and anthracene which may have a substituent, Ar3 represents an aryl group which may have a substituent, R1 to R3 each independently represent at least one group selected from the group consisting of a hydrogen atom, an alkyl group, and a phenyl group which may have a substituent, X represents a phenylene group which may have a substituent, a naphthylene group, or a single bond, n represents an integer in a range of 0 to 3, and at least one of Ar1 and Ar2 is at least one group selected from the group consisting of a phenyl group which may have a substituent, a naphthyl group which may have a substituent, and anthracene which may have a substituent and Ar1 and Ar2 may be bonded via a carbon atom, an oxygen atom or a sulfur atom, or directly bonded to each other to form a ring).
