Abstract
A process for producing toner particles, in which toner particles are produced by polymerizing a polymerizable monomer composition containing at least a polymerizable monomer in an aqueous medium in a vessel, is provided. In this process, a resin composition containing a THF-insoluble resin component, which is a resin component generated in the process for producing toner particles, is kneaded. Then, the kneaded material and the polymerizable monomer are mixed together, and the resulting polymerizable monomer is polymerized to produce toner particles. For the resin composition, toner particles different from those having desired property, deposits on the vessel where the polymerization reaction occurred, or the like is used.
