Abstract:
Methods for producing a polymerized toners are provided, where, a dispersion including colored polymer particles obtained by polymerizing a polymerizable composition is treated stably in the process of reducing the remaining monomer, the resultant polymerized toners include a sufficiently low content of remaining monomer, and the resultant polymerized toners have excellent properties and are useful as developers for printing and copying. In the process of reducing the remaining monomer, the dispersion of the colored polymer particles is treated by stripping in the presence of a specific antifoaming agent.
