To provide a toner production method excellent in fixing property and durability / fixing resistance in an environment. In the method for producing a toner, at least a binder resin, a colorant, and a release agent are melt-kneaded with a kneader, then pulverized and classified, and then the inorganic fine particles are adhered to produce the toner. The addition amount x (parts by mass) is 2 to 8 parts by mass with respect to 100 parts by mass of the binder resin, the kneader has a barrel and a screw, and the addition amount x of the release agent and The release agent toner is obtained by setting a supply amount F (Kg / h) to the barrel, a temperature T (° C.) of the barrel, and a rotation speed N (rpm) of the screw within a specified range. The surface exposure amount y (mg / g) satisfies 17.5 ≦ y ≦ 25.0. [Selection] Figure 1 |
