Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for producing toner by which the toner is obtained with high yield without causing flocculated substance in the case of mixing coloring particles with an additive, and a white stripe and fogging are hardly caused even when performing durable printing. SOLUTION: In the case of mixing the coloring particles with the additive by a mixer equipped with a stirring blade rotated at high speed, the flow rate of gas for sealing a shaft part is set to 0.4 to 3 m /hr and the circumferential speed of the edge of the stirring blade is set to 20 to 50 m/s, whereby the toner is produced.
