PURPOSE:To provide a dispersion method having high dispersion ability and not causing stains by incorporating a step for treating a photosensitive fluid in a dispersing device made of a ferromagnetic material and a step for passing this photosensitive fluid treated in said step through a magnetic field. CONSTITUTION:An electrophotographic dispersing device is provided with a cylindrical vessel 1 made of a nonmagnetic material, and a cylindrical ring 3 is arranged detachably on the outer circumference of the vessel 1 and provided with a magnet 4 on the inner wall. A photosensitive fluid 5 is contained in this vessel 1, and it is dispersed in advance in a pot made of a ferromagnetic material, such as iron or nickel, and in a ball mill dispersing machine 10. The vessel 1 freed of pollutants 51 is again supplied with another dispersed photosensitive fluid 5 from the dispersing machine 10. In this case, since the pollutants 51 are attracted with the magnet 4 located on the outer circumference of the vessel 1, this dispersion method has high dispersion performance and generates no pollutant. |
