Abstract
Regarding a method for manufacturing an electrostatic latent image developing toner, which includes a process for aggregating particulates of components such as a binder resin, a colorant, and a releasing agent, a dispersion solution of binder resin particulates obtained by a specific method is used. The dispersion solution of the binder resin particulates are prepared as an oil-in-water emulsion containing particulates including the binder resin by mixing the binder resin, which is polyester resin, in a molten state with an organic base in a liquid state so as to neutralize the binder resin and subsequently mixing a resin molten solution with water. The amount of use of the organic base is 6 parts by mass or more with respect to 100 parts by mass of the binder resin. The degree of neutralization of the binder resin neutralized by the organic base is 100% or more.
