Production process of toner for electrostatic image development |
摘要 |
<p>Disclosed is a production process of a toner for electrostatic image development, by which excellent toner particle size-controlling ability and moreover the sharpening of a particle size distribution are achieved. The production process is a production process of a toner for electrostatic image development, which is composed of toner particles containing at least a binder resin. The process has an aggregating and fusion-bonding step of adding a aggregating agent containing polysilicato-iron into an aqueous medium in which fine binder resin particles formed of the binder resin have been dispersed, thereby aggregating the fine binder resin particles, and an aggregation stopper-adding step of adding an aggregation stopper composed of a polyvalent organic acid or a salt thereof. In the production process of the toner for electrostatic image development, the polyvalent organic acid or the salt thereof is preferably an amino acid or a salt thereof.</p> |
