Abstract:
1. A method for manufacturing a toner, comprising: coagulating resin particles including at least binder resin, and wax particles having a diameter in a range of 30 to 600 nm obtained from slurry containing wax coarse particles by a high-pressure homogenizer method; and heating a resulting coagulated product, wherein the high-pressure homogenizer method includes a pulverizing step for obtaining heated and pressurized slurry containing wax particles by passing the slurry containing wax coarse particles through a pressure-resistant nozzle under heat and pressure and pulverizing the wax coarse particles; a cooling step for cooling down the slurry obtained at the pulverizing step; and a depressurizing step for gradually depressurizing the slurry cooled down at the cooling step to a pressure level at which no bubbling is caused.
