    Abstract: In a process for producing an electrophotographic photosensitive member, in particular, a process of forming a charge transporting layer, a production process is provided by which the stability of a charge transporting layer coating fluid even after its storage for a long time is improved so as to form a coat for a charge transporting layer having a high uniformity. In a process for producing an electrophotographic photosensitive member having a charge transporting layer on a support, a production process is used in which a coat of (i) a liquid dispersion comprised of particles containing a charge transporting material, particles containing a binder resin, and an aqueous dispersion medium, or (ii) a liquid dispersion comprised of particles containing both a charge transporting material and a binder resin, and an aqueous dispersion medium, is formed on the support and then the coat is heated at a temperature not less than the melting point of the charge transporting material to form the charge transporting layer.
