Electrophotographic photoreceptor, method of producing electrophotographic photoreceptor, image forming apparatus, and process cartridge

An electrophotographic photoreceptor comprising:

• a conductive substrate;
• and
• a photosensitive layer on the conductive substrate,
• wherein:
• a layer having an outermost surface of the photoreceptor contains a copolymer obtained by polymerizing a crosslinkable charge transport material having an aromatic group and a —CH2OH group with a crosslinkable charge transport material having a reactive alkoxyl group;
• the crosslinkable charge transport material having an aromatic group and a —CH2OH group is a compound represented by the following Formula (I-1):
• F1—(L1—OH)n (I-1),
• where:
• F1 represents an organic group derived from a compound having a hole transport property and an aromatic group,
• L1 represents a linear or branched alkylene group having from 1 to 5 carbon atoms, and
• n represents an integer of from 1 to 4;
• the crosslinkable charge transport material having the reactive alkoxyl group is a compound represented by the following Formula (I-2):
• F2—(L2—OR)m (I-2)
• where:
• F2 represents an organic group derived from a compound having a hole transport property,
• L2 represents a linear or branched alkylene grow having from 1 to 5 carbon atoms,
• R represents an alkyl group, and
• m represents an integer of from 1 to 4;
• and
• the layer having the outermost surface satisfies the following Formula (1):
• (Peak 2)/(Peak 1)≦0.05 (1),
• where:
• Peak 1 represents a peak area of an absorption peak (from about 1550 cm−1 to about 1650 cm−1) of stretching vibration of an aromatic group, which is obtained when an infrared absorption spectrum of the layer having the outermost surface is measured, and
• Peak 2 represents a peak area of an absorption peak (from about 1670 cm−1 to about 1710 cm−1) of aromatic aldehyde, which is obtained when the infrared absorption spectrum of the layer having the outermost surface is measured.
