Abstract
In a pigment depositing device for forming a recording layer of an optical recording medium, there is used an organic pigment of powder state, in which the diameter of each of particles of the organic pigment is uniform. In consequence, occurrence of splash is prevented when the organic pigment is heated by an electrical heater so that it is prevented that the particles of the organic pigment adhere to a substrate. Moreover, fluidity of the organic pigment in an organic pigment feeding device is raised so that the organic pigment is smoothly fed.
