A toner can be produced by dispersing a colorant in a dispersion medium essentially composed of a polymerizable monomer by using a media-type dispersing device at a tip speed of a stirring body of 3 to 20 m/s with a residence time being 0.03 to 0.5 hour to obtain a monomer composition A; dispersing or dissolving a charge control agent in a dispersion medium to obtain a monomer composition B; dispersing or dissolving a parting agent in a dispersion medium to obtain a monomer composition C; mixing or dispersing the monomer composition A, the monomer composition B and the monomer composition C in a dispersion medium to obtain a polymerizable composition D; and homogenizing the composition D in an aqueous dispersion medium containing a dispersion stabilizer to generate droplets; polymerizing the droplets to obtain colored polymer particles; and attaching an outer-additive on the colored polymer particles.
