发明名称 METHOD FOR PRODUCING TONER, TONER, TWO COMPONENT DEVELOPER, IMAGE FORMING APPARATUS, AND PROCESS CARTRIDGE
摘要 PROBLEM TO BE SOLVED: To provide a method for producing toner having excellent cleaning properties and also capable of improving a yield upon the production of toner. SOLUTION: In the method for producing toner comprising: a granulation step where an organic solvent phase composed of a toner composition at least including a binding resin and/or a monomer for a binding resin is emulsified/or dispersed into a water base medium phase, so as to granulate toner; and a classification step of classifying the toner for obtaining toner with prescribed particle diameters, fine powder as the toner with particle diameters smaller than the above prescribed particle diameters removed by the above classification step when the above toner is produced in an another lot is mixed, dispersed or dissolved into the organic solvent phase. Also disclosed are toner produced by the method, a two component developer comprising the toner, and an image forming apparatus and a process cartridge using the toner. COPYRIGHT: (C)2008,JPO&INPIT
