Abstract
A method for manufacturing a polymerized toner comprising a process for forming fine droplets of a polymerizable monomer composition in an aqueous dispersion medium, and a process for polymerizing the polymerizable monomer composition after the process for forming fine droplets; wherein the process for forming fine droplets has the steps of: preparing an agitating apparatus having an agitator equipped with an agitating blade or rotor and a dispersion supply tank; providing a polymerizable monomer composition and an aqueous dispersion medium into the dispersion supply tank; then, mixing the polymerizable monomer composition and the aqueous dispersion medium by the agitator to obtain a dispersion of fine droplets; and the relationship between the peripheral velocity of the agitating blade or rotor of the agitator and the number of circulations of the dispersion is controlled.
