Abstract
The present invention aims to provide a method of producing a polymerized toner which is small in an amount of a microparticle produced as a by-product and an amount of a polymerizable monomer remained, generates no filming upon printing and is excellent in printing durability, and provides a method of producing a polymerized toner comprising the steps of: (A) preparing a polymerizable monomer composition containing at least a polymerizable monomer and a colorant; (B) obtaining a polymerizable monomer composition dispersion by adding the polymerizable monomer composition in an aqueous medium containing a dispersion stabilizer, thereby to form droplets of the polymerizable monomer composition; and (C) obtaining a colored polymer particle by heating the polymerizable monomer composition dispersion to polymerize the polymerizable monomer composition, wherein the polymerizable monomer composition dispersion contains a water-soluble polymerization inhibitor and a thiuram disulfide.
