ABSTRACT:
Disclosed herein is an electrophotographic photoreceptor having on a conductive base at least one charge generation layer and at least one charge transport layer, said charge transport layer having the thickness of 27 .mu.m or above and being formed with a coating solution containing a condensation polymer of the viscosity-average molecular weight of 15,000 to 25,000 as a binder resin according to the dip coating method. The electrophotographic photoreceptor according to the present invention has the excellent durability because the resultant charge transport layer has the increased and uniform thickness without changing the electric properties, especially the charged potential.
