Electrophotographic photosensitive member and electrophotographic process using the same
 An electrophotographic photosensitive member comprising an organic photoconductive material has a structure that a charge transport layer containing a charge transporting material and a binder and a charge generation layer containing a charge generating material and a binder are laminated in succession in this order on a conductive substrate. The weight ratio of said charge transporting material to said binder in said charge transport layer is not less than 12/10 and said charge generation layer contains a charge transporting material.
