Electrophotographic photoconductor, process cartridge, and image forming apparatus

An electrophotographic photoconductor comprising:

• a conductive substrate;
• and
• an outermost surface layer formed on the conductive substrate and containing a binder resin and a copolymer derived from a reactive monomer having charge transport property and a reactive monomer having no charge transport property, the copolymer having a side chain with 4 or more carbon atoms in a constitutional unit derived from the reactive monomer having no charge transport property,
• wherein the reactive monomer having no charge transport property has a bisphenol skeleton, and
• the copolymer contains a constitutional unit represented by general formula (1-1) below and derived from the reactive monomer having charge transport property and a constitutional unit represented by general formula (1-2) below and derived from the reactive monomer having no charge transport property,
• where in general formulas (1-1) and (1-2), R1 and R2 each independently represent hydrogen or an alkyl group having 1 to 4 carbon atoms, R3 represents an organic group having 4 or more carbon atoms and no charge transport property, X represents a divalent organic group having 1 to 10 carbon atoms, a is 0 or 1, and CT represents an organic group having a charge transport skeleton.
