ABSTRACT:
A process for making a toner. The process includes mixing a toner resin and a colorant; extruding the resin and colorant mixture; attriting the resin and colorant mixture; classifying the attrited particles into particles averaging 4 to about 10 microns in size; and blending sufficient surface additive particles and the classified particles in a high intensity blender such that the weight of attached surface additives is greater than two (2) of the weight of the classified particles and such that the blending is intense enough to yield Additive Adhesion Force Distribution percent values after 10 minutes of sonification and 12 kilojoules of energy greater than 40 percent.
