Electrophotographic photoconductor, method for preparing the same, process cartridge, and image forming apparatus

An electrophotographic photoconductor comprising:

• a conductive substrate;
• and
• an outermost surface layer on the conductive substrate, the outermost surface layer containing
• a copolymer (a) that includes a constitutional unit represented by general formula (1) below derived from a reactive monomer having charge transport property and a constitutional unit represented by general formula (2) below derived from a reactive monomer having no charge transport property:
• where, in general formulae (1) and (2),
• R represents an organic group having no charge transport property;
• R1 and R2 each independently represent hydrogen or an alkyl group having 1 to 4 carbon atoms;
• X represents a divalent organic group having 1 to 10 carbon atoms;
• a represents 0 or 1;
• and
• CT represents an organic group having a charge transport skeleton, and
• a polymer prepared by polymerizing, in the presence of the copolymer (a), a reactive monomer (b) that has a solubility parameter (SP value) different from a solubility parameter (SP value) of the reactive monomer having no charge transport property by about 2 (cal/cm3)1/2 or less,
• wherein a ratio of a constitutional unit derived from the reactive monomer having no charge transport property in the copolymer (a) is about 10 mass % or less.
