EMULSION AGGREGATION TONER PROCESS COMPRISING DIRECT ADDITION OF SURFACE-TREATED PIGMENT

摘要

A method of making a toner that includes adding pigments into an emulsion aggregation toner without first preparing a pigment dispersion. The method eliminates the pigment dispersion step in the manufacture of emulsion aggregation toilers by surface-treating pigments. Dry surface-treated pigments can be directly incorporated into the toner prior to aggregation in the aggregation coalescence process without the need to first prepare aqueous pigment dispersions.
