ABSTRACT:
A process for producing a developer for electrostatic latent images comprising adding a solution (A) of a high-molecular weight compound having electron-donating functional groups dissolved in an organic solvent (1) which is a good solvent for the high-molecular weight compound to an organic solvent (2) in which the high-molecular weight compound is substantially insoluble, thereby depositing the high-molecular weight compound in a finely divided particle form, wherein an organic resin which is soluble in both of organic solvent (1) and organic solvent (2) is dissolved in at least one of solution (A) and organic solvent (2).
