Method for producing a negatively charged polymerized toner

Good balance of high temperature preservability and low temperature fixability to provide a method of manufacturing has excellent thin-line reproducibility and negatively charged polymerized toner occurs with less fog. At least the first-stage polymerizable monomer, a first stage polymerizable monomer composition containing a colorant and a charge control agent, by suspending in an aqueous dispersion medium containing a dispersion stabilizer, the first stage polymerization suspension step of the droplets of sex monomer composition to obtain a suspension obtained by dispersing, first stage polymerization step of performing suspension polymerization in the presence of a polymerization initiator with the suspension, and the first-stage polymerization when the polymerization conversion in step became 5% to 95%, negative with even, second stage polymerization step of performing suspension polymerization by adding a second stage polymerizable monomer mer satisfying the following formula (1) a method of manufacturing a chargeable polymerized toner, the charge control agent, and a vinyl aromatic hydrocarbon (meth) acrylate and a sulfonic acid group-containing (meth) obtained by copolymerizing acrylamide and a sulfonic acid group-containing (meth) copolymerization ratio of acrylamide 0.8 to 4 Negatively charged polymers method for producing a toner which is a 0 mass%. Tg (In the above formula (1), Tg
