Abstract:
1. A toner manufacturing method comprising: a kneading step of kneading at least a binder resin and a colorant; a granulation step of mixing a resin kneaded product obtained through the kneading step with an aqueous medium containing a dispersant and water, and heating the aqueous medium contained in an obtained admixture to a predetermined temperature while stirring the admixture so as to form resin particles containing the colorant within the aqueous medium; and a separation step of separating the formed resin particles containing the colorant from the aqueous medium, wherein, in the granulation step, the admixture is stirred by an stirring apparatus comprising a vessel for housing therein the admixture; an stirring space forming member for partitioning a space within the vessel into an stirring space in which the admixture is stirred and a space outside the stirring space, the stirring space forming member having an admixture discharge hole for providing communication between the stirring space and the space outside the stirring space; and an stirring section for stirring the admixture accommodated in the stirring space, wherein a loss elastic modulus G″ of the resin kneaded product is kept at or below 10
