Abstract
A color toner for developing an electrostatic image has color toner particles containing a binder resin and a colorant. The color toner particles have been obtained by mixing a mixture containing at least a polymerizable monomer, the colorant and a polymerization initiator to prepare a polymerizable monomer composition, dispersing the polymerizable monomer composition in an aqueous medium to carry out granulation, and polymerizing polymerizable monomers in the aqueous medium. The colorant comprises fine organic pigment particles or fine organic dye particles having an acetic acid adsorption heat in n-heptane of from 0.1 mJ/m.sup.2 to 80 mJ/m.sup.2.
