摘要： A method for preparing in high productivity and stably an electrophotographic photosensitive member having depressed portions on its surface, is provided. The method is characterized in that a coating liquid for a surface layer which includes a solvent including a hydrophilic solvent and a hydrophobic solvent and a polymer compound soluble in the hydrophobic solvent is used; the hydrophilic solvent has a boiling point equal to or higher than that of the hydrophobic solvent; the hydrophilic solvent has a dipole moment of 0 or more and less than 2.8, obtained by a structure optimized calculation using a semiempirical molecular orbital calculation; the total mass of the hydrophobic solvent is 50 mass % or more and less than 100 mass % of the total mass of the solvent included in the coating liquid for a surface layer; and after the coating liquid for a surface layer is applied, the depressed portions are formed by condensation on the surface on which the coating liquid for a surface layer is applied.
