Abstract
The present invention provides a method of producing an electrophotographic photosensitive member in which the amount of an organic solvent to be used for a coating solution for a charge transporting layer is reduced, and the stability of the coating solution for a charge transporting layer after preservation for a long time is improved, enabling formation of a charge transporting layer having high uniformity. The method includes: preparing a solution containing a charge transporting substance, a resin having a carbonyl group, and at least one compound selected from the group consisting of a compound represented by the formula (A), a compound represented by the formula (B), a compound represented by the formula (C), a compound represented by the formula (D), and a compound represented by the formula (E); dispersing the solution in water to prepare an emulsion; forming a coat by using the emulsion; and heating the coat to form a charge transporting layer.
