Patent ID: 8163458

Claim:
A method of manufacturing a toner comprising: a preliminary pulverizing step of pulverizing a melt-kneaded product of a toner raw material in a liquid to obtain a coarse powder slurry containing a coarse toner powder the melt-kneaded product of the toner raw material being pulverized in the absence of a dispersant; a finely pulverizing step of passing the coarse powder slurry obtained in the preliminary pulverizing step under heating and pressure through a pressure resistant nozzle, thereby further pulverizing the coarse toner powder to obtain a fine powder slurry containing a fine toner powder with a smaller volume average particle size than that of the coarse toner powder and in a heated and pressurized state; a cooling step of cooling the fine powder slurry obtained in the finely pulverizing step; and a depressurizing step of depressurizing the fine powder slurry cooled in the cooling step.
