Abstract
Provided is a process for producing an electrophotographic photosensitive member having high uniformity of the surface of its undercoat layer by which the usage of an organic solvent is reduced and the stability of an application liquid for an undercoat layer after its long-term storage is improved in the step of forming the undercoat layer. The process for producing an electrophotographic photosensitive member includes the steps of: preparing a solution containing a liquid whose solubility in water at 25° C. and 1 atmosphere is 3.0 mass % or less and an electron transporting substance; preparing an emulsion by dispersing the solution in water; forming a coat of the emulsion on a support; and forming the undercoat layer by heating the coat.
