摘要:
A method for manufacturing a toner includes a pre-mixing step and a coating step. In the pre-mixing step, a secondary aggregate of the fine resin particles is disaggregated, while toner base particles and fine resin particles are mixed and stirred using a rotary stirring apparatus. Thus obtained disaggregated fine resin particles are fixed to the surface of the toner base particle. Thus, a fine resin particle-fixed toner is obtained. The rotary stirring apparatus includes a rotary stirring section, a temperature regulation section, a circulating section, and a spraying section. In the coating step, a liquid is sprayed to the fine resin particle-fixed toner with the spraying section using the rotary stirring apparatus. Thus, a film of the fine resin particles is formed. In the pre-mixing step and the coating step, temperature regulation is conducted in the temperature regulation section.
