Abstract: An electrophotographic photoreceptor having a good printing quality can be provided by a photoreceptor comprising a charge transporation layer composed of a photosensitive material containing a hole mobility enhancing material. Thus, in accordance with an emboidment of the invention, it is possible to rapidly attenuate negative charge and to obtain a photoreceptor having a good printing quality by adding a hole mobility enhancing material to the CTL without producing a difference in print density between regions of the photoreceptor between sheets of paper and covered with a sheet. Some metal oxides and acids, such as WO.sub.2, WO.sub.3, MnO.sub.4, H.sub.3 PO.sub.3, H.sub.2 SO.sub.3 and HAsO.sub.2, are found to have a hole mobility enhancing effect to a CTL of a selenium alloy. Some metal elements, such as Sn, Co, Pb, Fe, Cu, Hg, Ag and Ce, are also found to have a hole mobility enhancing effect to the CTL. Finally, halogen elements are also found to have a hole mobility enhancing effect to the CTL.
