Abstract:
1. A method for manufacturing a resin-layer coated toner using a rotary stirring apparatus that comprises a circulating section including a rotary stirring section having a rotary disc around which rotary blades are installed and a rotary shaft, and a powder passage having a rotary stirring chamber and a circulation tube, the circulating section repeatedly circulating toner base particles and fine resin particles by the rotary stirring section inside the powder passage to return to the rotary stirring chamber; a temperature regulation section provided at least on a part of the powder passage for adjusting a temperature in the powder passage and the rotary stirring section to a predetermined temperature; a spraying section that includes a two-fluid nozzle for spraying to toner base particles and fine resin particles in a fluidized state a liquid substance to plasticize such particles by carrier gas; and an exhausting section for exhausting carrier gas including the gasified substance to the outside of the powder passage, the method comprising: circulating the carrier gas in the powder passage; and continuously exhausting the carrier gas including the gasified substance to the outside of the power passage through the exhausting section, pressure P
