Emulsion aggregation process for forming polyester toners |
摘要 |
A process for forming toner particles includes aggregating the toner particles by adding an aggregating agent to a latex emulsion of resin having a colorant mixed therein, the adding being done under adding conditions of agitation and a temperature above a glass transition temperature of the resin, wherein the adding of the aggregating agent comprises first introducing at least about 40% by weight of a total amount of aggregating agent to be added at a rapid introduction rate and subsequently adding a remaining portion of the aggregating agent at a continuous addition rate slower than the rapid introduction rate. The particles are subsequently cooled to a temperature below the glass transition temperature of the resin when particles have been grown to the desired size.
