An electrophotographic photoconductor that stabilizes electrical performances and prevents generation of image faults such as memories, irrespective of types of organic materials of resin binder and charge transport material, and variation of temperature and humidity of the operation environment. An electrophotographic photoconductor includes at least a photosensitive layer formed over a conductive substrate, wherein the photosensitive layer contains a cyclohexane dimethanol-diaryl ester compound represented by the formula (I): in formula (I), each of R1 through R10 represents independently, a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group of carbon number of from 1 to 5, a substituted or unsubstituted aryl group, or a substituted or unsubstituted alkoxy group of carbon number of from 1 to 5.
