METHOD OF PREPARING ENVIRONMENT-FRIENDLY TONER

摘要

A method of preparing a toner. A toner having a low residual VOC content, a narrow particle size distribution, excellent fixing properties at low temperature, and high image quality may be prepared using the method by which a polyester resin dispersion is prepared by adding ingredients to a single reactor in a predetermined order.

1. A method of preparing a toner, the method comprising:
adding a polyester resin and an organic solvent to a polar solvent comprising a surfactant and a dispersion stabilizer while stirring; heating the mixture to prepare a polyester resin dispersion, in which an amount of the residual organic solvent is less than 10,000 wtppm; mixing the polyester resin dispersion with a colorant dispersion and a wax dispersion; aggregating toner particles by adding an aggregating agent to the mixture; and coalescing the aggregated toner particles.
