PURPOSE: A process for preparing a polymerized toner and the polymerized toner prepared thereby are provided to effectively manufacture a toner of a narrow particle-size distribution and to facilitate the control of toner particle size distribution. CONSTITUTION: A process for preparing a polymerized toner comprises: forming an aqueous dispersion medium comprising calcium phosphate; forming a monomer mixture of a polymer charge control agent having weight average molecular weight of 10,000 to 20,000, pigment, and a monomer for a binder resin; dispersing the monomer mixture into the aqueous dispersion medium in the form of droplets; and suspension-polymerizing the monomer mixture dispersed in the form of droplets, wherein 2 to 6 parts by weight of the calcium phosphate and 0.6 to 10 parts by weight of the charge control agent are used, based on 100 parts by weight of the monomer mixture.
