Production manner of the toner for electrostatic charge image development and comminution classification device null for the toner

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a toner which has little inclusion of coarse particles and makes it possible to obtain good image quality.;SOLUTION: The method for manufacturing the electrostatic charge image developing toner comprises pulverizing a coarsely pulverized toner containing at least a resin and coloring matter, then classifying the same. The pulverization is performed by introducing the coarsely pulverized toner into a mechanical pulverizer having a rotor rotating around a revolving shaft and having rugged parts on its outer surface, a liner fitted to the outer side of the rotor and having rugged parts on its inner surface, and a pulverizing space formed between the outer surface of the rotor and the inner surface of the liner. The classification is performed by a simultaneous classifying machine for multiple products utilizing a Coanda effect.;COPYRIGHT: (C)2004,JPO
