Patent ID: 8652746

Claim:
A process for producing a toner for electrophotography, comprising: emulsifying a mixed polyester comprising (1) an amorphous polyester containing a constitutional unit derived from a trivalent or higher-valent carboxylic acid in an amount of from 6.28 to 12.0 mol % on the basis of whole constitutional units of the whole amorphous polyester and (2) a crystalline polyester, in an aqueous medium in a single vessel, and at a temperature of not lower than the softening point of the crystalline polyester and not higher than the softening point of the amorphous polyester, wherein the crystalline polyester contains a constitutional unit derived from an aromatic carboxylic acid component in an amount of from 50 to 100 mol % on the basis of a whole carboxylic acid component constituting the crystalline polyester, and the following: aggregating at least the polyester particles present in said dispersion of the polyester particles obtained from said emulsifying to obtain a dispersion of aggregated particles, and coalescing the aggregated particles present in the dispersion of the aggregated particles obtained from said aggregation.
