A method for producing a polymerized toner comprising a step of polymerizing a polymerizable monomer composition in an aqueous dispersion medium in the presence of a polymerization initiator to obtain a dispersion liquid of colored polymer particles and a stripping step of injecting a gas comprised of air or an inert gas into the dispersion liquid of the colored polymer particles while stirring the dispersion liquid in an evaporator and the flow rate of the gas injected per weight of the colored polymer particles being 0.05 to 4 L/(hr·kg), the pressure of the vapor phase of the evaporator being 5 to 80 kPa.
