ABSTRACT:
A charge control resin composition for positive or negative charge, which is prepared either by mixing and kneading a charge control resin for positive or negative charge with a colorant, or by mixing and kneading the above combination further with a charge control resin for opposite charge or a charge control resin composition for opposite charge; wherein colorant particles are finely dispersed as desired. The resultant mixture is mixed with a polymerizable monomer to obtain polymerizable monomer composition. Then, the polymerizable monomer composition is dispersed or emulsified in an aqueous dispersion medium containing a dispersion stabilizer, and polymerized to obtain a toner.
