A process of producing an electrophotographic photosensitive member which can be used in many copying machines and printers is here disclosed, and this process comprises the step of spraying two or more kinds of charge generating materials on an electroconductive support by a coating apparatus in which each of independent spray devices is disposed for each of the charge generating materials, in order to form a photosensitive layer containing the two or more kinds of charge generating materials on the electroconductive support, whereby the electrophotographic photosensitive member is obtained in which the photosensitive layer is formed on the electroconductive support.
