<p>The present invention provides a method for producing a toner that can suppress the production of the decomposition products derived from a polymerization initiator, and can suppress the remaining presence, in the toner particles, of the unreacted polymerizable monomer and decomposition product residues. On the basis of this method, the present invention provides a toner that is excellent in triboelectric charging stability and can yield stable images over a long term. The present invention provides a method for producing a polymerized toner including a step of producing a polymerized toner particle by dispersing in an aqueous medium a polymerizable monomer composition including at least a polymerizable monomer and a colorant and by polymerizing the polymerizable monomer by using a polymerization initiator in the aqueous medium, the method being characterized in that the polymerization initiator has a structure represented by the following General Formula: (wherein R1 and R2 each independently represent an optionally branched or substituted aliphatic hydrocarbon group having 1 to 6 carbon atoms, and R3 represents an optionally branched aliphatic hydrocarbon group having 3 to 12 carbon atoms).</p> |
