Abstract
Provided are a method of producing an electrophotographic photosensitive member, particularly, a method of producing an electrophotographic photosensitive member and an organic device by which, in a method of forming a charge transporting layer, the stability of an application liquid for the layer after long-term storage is improved while the usage of an organic solvent in the application liquid is curtailed, and the layer having high uniformity is formed. The method is a method of producing an electrophotographic photosensitive member which includes a support and a charge transporting layer formed thereon, the method including: preparing a solution including: a first liquid whose solubility in water under 25° C. and 1 atmosphere is 1.0 mass % or less; a second liquid whose solubility in water under 25° C. and 1 atmosphere is 5.0 mass % or more; a charge transporting substance; and a binder resin; preparing an emulsion by dispersing the solution in water; forming a coat for the layer on the support by using the emulsion; and forming the layer by heating of the coat.
