PROBLEM TO BE SOLVED: To provide a method of manufacturing small-sized toner, having a particle size of about 5μm suitable for higher definition and higher resolution of an image, by preventing generation of bubbles when applying a shear force with respect to the method of manufacturing toner where granulation is performed by using the shear force. SOLUTION: When performing granulation by mixing a compound of toner raw material with water dispersions of a dispersant, the inner part of a granulation system is heated and pressurized, a high-speed rotary dispersion type granulator 1, that includes a cylindrical pressure vessel 2, a rotating rotor 3, follow-up screens 4, 5, and a fixed screen 6, is used as a granulator, and an impact force, as well as, the shear force is applied to the compound of the toner raw material.
