<p>PROBLEM TO BE SOLVED: To provide a method for manufacturing toner by which a toner having sharp distribution of the grain size can be obtained in a high yield and the toner can be industrially and continuously produced. SOLUTION: The method for manufacturing a toner includes processes of melting and kneading at least a coloring agent and a binder resin, cooling, then roughly pulverizing the obtained kneaded material into particles of the maximum <=5 mm particle size, and then finely pulverizing and classifying to obtain a toner having 3 to 20μm volume average particle size. The method also includes a process of stirring and mixing the roughly pulverized material with a fluidity imparting agent.</p> |
