Abstract PROBLEM TO BE SOLVED: To provide a process of producing toners from polyester resin latexes, which comprises phase inversion emulsification for conversion to a uniform dispersion of a polyester latex, or a latex.SOLUTION: A process includes: dissolving a polyester resin in an organic solvent to form a solution, the polyester resin including a latex-destabilizing cation; removing substantially all of the latex-destabilizing cation; neutralizing the solution of the polyester resin; adding a sufficient amount of water to the neutralized solution to form an emulsion; and removing a portion of the organic solvent from the emulsion to form a latex of the polyester resin. 【課題】ポリエステル樹脂ラテックスよりトナーを製造するプロセスにおいて、転相乳化によってポリエステルラテックスの均一な分散物またはラテックスに変換することを提供する。【解決手段】プロセスは、ラテックスを不安定化するカチオンを含むポリエステル樹脂を有機溶媒に溶解して溶液を作成することと、ラテックスを不安定化するカチオンの実質的にすべてを除去することと、ポリエステル樹脂の溶液を中和することと、中和した溶液に、エマルションを生成するのに十分な量の水を加えることと、エマルションから有機溶媒の一部を除去し、ポリエステル樹脂のラテックスを作成することとを含む。【選択図】なし
