| 摘要 |
The present invention relates to a process for producing a toner which includes the steps of emulsifying a resin binder containing a polyester in an aqueous medium to prepare an emulsion of the resin binder and adding a water-soluble nitrogen-containing compound having a molecular weight of 350 or less to the emulsion obtained in the previous step to aggregate emulsified particles contained in the emulsion. According to the present invention, the shape of toner particles can be controlled simply for a short production time by using a resin binder containing a polyester and using substantially no organic solvent, and further a toner having a narrow and sharp particle size distribution can be produced.
