Method of producing toner for developing latent electrostatic images
 A method of producing a toner for developing latent electrostatic images is disclosed, which comprises the steps of dispersing resin particles comprising a resin in an organic solvent in which the resin is not dissolved; dissolving a dye in the organic solvent before or after dispersing the resin particles in the organic solvent to prepare a dispersion in which the resin particles and the dye are contained, thereby dying the resin particles with the dye; and removing the organic solvent from the dispersion, wherein the ratio of the solubility [D.sub.1 ] of the dye in the organic solvent to the solubility [D.sub.2 ] of the dye in the resin of the resin particles, [D.sub.1 ]/[D.sub.2 ], is not more than 0.5.
