<p>PURPOSE: To provide a process for producing electrostatic charge image developing toners which improves production yield. CONSTITUTION: The pulverized raw material formed by melting and kneading a compsn. contg. a binder resin and coloring agents and solidifying the kneaded matter by cooling is introduced into a first classifying means, where the kneaded matter is classified to coarse powder and fine powder. The classified coarse powder is pulverized by a pulverizing means and is thereafter circulated to the first classifying means. The fine powder classified in the first classifying means is introduced into a second classifying means, where the classified coarse powder is made into a product. Further, the fine powder classified in the second classifying means is introduced into a third classifying means and is made into the classified coarse powder.</p> |
