摘要：
A method of producing a toner composition, including:
stirring and mixing toner particles comprising a binder resin, a colorant and a release agent with a charge controlling agent in a fluidizing and stirringmixer comprising a rotor having a stirring blade to fix the charge controlling agent on the surface of the toner particles,
wherein the rotor rotates at a peripheral speed of from 65 to 120 m/s at an environmental temperature (T) in the fluidizing and stirring mixer, satisfying the following relationship: Tg-10 > T > Tg-35 (°C) wherein Tg represents the glass transition temperature of the binder resin.
