Abstract: PROBLEM TO BE SOLVED: To provide a toner manufacturing method for manufacturing the toner that can be fixed at a low temperature and can form a high definition, high resolution, and high quality image with a narrow particle size distribution width in a state where reduction in production efficiency is prevented. SOLUTION: The method of manufacturing toner includes a toner fluid dispersion-preparing step and a drying step. In the toner fluid dispersion-preparing step, toner fluid dispersion is prepared where toner mother particles containing binder resin having a glass transition temperature of 60°C or lower are dispersed at content of 10 to 40 wt.% in aqueous medium. In the drying step, dried toner mother particles are obtained by atomizing the toner fluid dispersion obtained in the toner fluid dispersion-preparing step into a drying chamber where pulse impulse wave is radiated at a temperature that is a glass transition temperature of the binder resin or higher and (glass transition temperature of the binder resin + 10)°C or lower.
