    摘要: A method for producing a toner, containing: dispersing, in an aqueous medium, an oil phase which contains an organic solvent, and a binder resin component contained in the organic solvent, where the binder resin component contains a crystalline polyester resin and an amorphous polyester resin; and removing the organic solvent from the dispersion to obtain the toner, in which the dispersing further contains heating and dissolving the crystalline polyester and the amorphous polyester in the organic solvent to obtain a solution, cooling the solution so as to recrystallize the crystalline polyester resin, and mechanically pulverizing the recrystallized crystalline polyester resin so as to obtain a crystalline polyester dispersion.

    摘要: The present invention provides a method for producing a toner, the method including: preparing a wax dispersion liquid by cooling a wax solution, in which a wax is heated and dissolved or dispersed in an organic solvent, in a container so that a standard deviation σ of a temperature distribution between a center portion of the container and an inner wall of the container is 0.5 or less and the cooling rate is 2.0° C./min or more, to precipitate wax particles in the wax solution; forming toner base precursor particles by adding an aqueous phase containing resin fine particles into an oil phase containing at least the wax dispersion liquid, a colorant and a binder resin and mixing the oil phase and the aqueous phase with each other; and preparing toner base particles by removing the solvent from the toner base precursor particles.
