PROBLEM TO BE SOLVED: To provide a method for manufacturing an electronic photosensitive material less in coating film defects by using an immersion coating system. SOLUTION: The method for manufacturing a electronic photosensitive material using the immersion coating system equipped with a circulation device is characterized by using a dispersion liquid obtained by dispersing together a binder resin, a titanyl phtahloyanine crystal which has a maximum diffraction peak at least at 27.2°as the diffraction peak (±0.2°) of a Bragg angle 2θwith a characteristic X-ray (wavelength 1.542Å) of CuKα, further has major peaks at 9.4°, 9.6°and 24.0°, has a peak at 7.3°as the diffraction peak on the lowest angle side, does not have a peak in a range of≥7.4 and≤9.4°and in which the average size of the primary particles is 0.2μm as a coating liquid for a photosensitive layer and by providing the circulation system of the coating system with a filter of 10μm in effective pore diameter.
