An electrophotographic photoreceptor is provided that can achieve reductions in the amount of wear in the photoreceptor surface while producing an excellent image on a long-term basis. Also provided are a method of producing the electrophotographic photoreceptor and an electrophotographic apparatus. The electrophotographic photoreceptor includes a conductive substrate; and a photosensitive layer provided on the conductive substrate and being composed of a resin having a molecular structure optimized using molecular dynamic calculations that is a helical structure, and having 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.
