Production process of polymerized toner

A process for producing a polymerized toner, comprising Production Step 1 of polymer particles, including a step of polymerizing a polymerizable monomer composition containing a colorant and a polymerizable monomer in the presence of a polymerization initiator in an aqueous dispersion medium;

• Stripping Treatment Step 2 of subjecting a dispersion containing the polymer particles to a stripping treatment to remove volatile organic components including an unreacted polymerizable monomer;
• and Collecting Step 3 of collecting the polymer particles from the dispersion after the stripping treatment, wherein in Stripping Treatment 2,
• (1) the dispersion containing the polymer particles is introduced into an evaporator,
• (2) the stripping treatment is conducted by a method, in which a gas is blown into the dispersion within the evaporator to discharge the volatile organic components including the unreacted polymerizable monomer out of the evaporator concomitantly with the gas, and
• (3) both inert gas and saturated steam are used as the gas blown into the dispersion.
