A method for producing a toner containing a toner particle containing a binder resin, a colorant and a crystalline substance, wherein the method includes the steps of: (I) setting a temperature of a dispersion, in which a coloring particle is dispersed with an aqueous medium, to TA(° C.), which is higher than the higher of a crystallization temperature Tc(° C.) of the crystalline substance and a glass transition temperature Tg(° C.) of the coloring particle, the coloring particle containing the binder resin, the colorant and the crystalline substance; (II) cooling the dispersion from the TA to a temperature equal to or lower than the Tg at a cooling rate of at least 5.0° C./min after the step (I); and (III) holding the dispersion in a temperature from Tg−10 to Tg+10 for at least 30 min after the step (II).
