METHOD FOR MANUFACTURING TONER, TONER, DEVELOPER, DEVELOPING DEVICE AND IMAGE FORMING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing toner, manufacturing toner including toner base particles uniformly covered with resin fine particles in a high yield by suppressing adhesion of the toner base particles to a device inner wall and generation of aggregated matter while holding a state in which the toner base particles are made to independently flow.

SOLUTION: The method for manufacturing toner uses a rotary stirring apparatus that includes: a circulating section for repeatedly performing circulation in a powder passage having a rotary stirring chamber and a circulation tube to return to the rotary stirring chamber by a rotary stirring section having a rotary disc around which rotary blades are installed and a rotary shaft; and a temperature adjusting section provided at least on a part of the powder passage for adjusting temperatures in the powder passage and of the rotary stirring section to a predetermined temperature, and includes: a temperature adjusting step; a fine resin particle adhering step; a spraying step; and a film forming step. The temperature in the powder passage is adjusted to the predetermined temperature by the temperature adjusting section in the fine resin particle adhering step, the spraying step, and the film forming step.
