The photosensitive layer contains charge generation substance, charge transport substance and a binder resin. The binder resin has a dispersion d1nullMz/Mw of at least 1.6, or a polydispersity d2nullMw/Mn of at least 2.0, each of d1 and d2 being an indicator of a range of molecular weight distribution converted to polystyrene standard, wherein Mz, Mw and Mn are a z-average molecular weight, a weight-average molecular weight, and a number-average molecular weight of the binder resin, respectively. The resulting electrophotographic photoconductor minimizes film abrasion and filming, allowing the photoconductor to possess stable characteristics in repeated use over long periods.
