Claim:
1. An electrophotographic photoreceptor, comprising: a conductive substrate; and a photosensitive layer provided on the conductive substrate and being comprised of a polyarylate resin that has a molecular structure optimized using molecular dynamic calculations that is a helical structure, and that has a value for a ratio r/I between the diameter (r) and helix pitch (I) of the helical structure that ranges from 0.04 to 1.0, wherein the polyarylate resin has repeat units represented by a chemical structural formula 1 as follows: where substructure formulas (A), (B), (C), and (D) each represent a structural unit that constitutes the resin; a, b, c, and d respectively represent mol % of the structural units (A), (B), (C), and (D); a+b+c+d is 100 mol %; R
