Claims
- 1. An improved toner made by an improved process, comprising:(a) forming toner particles averaging 4 to 10 microns in size and comprised of at least one toner resin and at least one colorant; and (b) blending sufficient surface additive particles and the toner particles in a high intensity blender for less than 10 minutes such that the weight of surface additives that become attached to toner particles is greater than three (3) percent of the weight of the classified particles wherein the blending is intense enough to yield Additive Adhesion Force Distribution (AAFD) percent values after 6 kJ of energy greater than 25 percent.
- 2. The improved toner made by the improved process of claim 1, wherein the step of forming further comprises:(a) mixing a toner resin and a colorant; (b) extruding the resin and colorant mixture; (c) attriting the resin and colorant mixture; and (d) classifying the attrited particles into particles averaging 4 to 10 microns in size.
- 3. The improved toner made by the improved process of claim 1, wherein the step of forming further comprises forming the toner particles using an emulsion/aggregation/coalescence process.
- 4. The improved toner of claim 1, wherein the weight of attached surface additives is greater than four (4) percent of the weight of the classified particles.
- 5. The improved toner of claim 1, wherein the weight of attached surface additives is greater than five (5) percent of the weight of the classified particles.
- 6. The improved toner of claim 1, wherein the weight of attached surface additives is greater than six (6) percent of the weight of the classified particles.
- 7. The improved toner of claim 1, wherein the blending is intense enough to yield MFD percent values after 3 kJ of energy is greater than 35 percent.
- 8. The improved toner made by the improved process of claim 1, wherein the step of forming further comprises:(a) forming polymeric latex particles using an emulsion process (b) aggregating polymer latex, colorant and wax particles (c) coalescing the aggregate to form the single toner particles (d) washing and drying the resulting toner particles.
- 9. An improved process for making toners, comprising:(a) forming toner particles averaging 4 to 10 microns in size and comprised of at least one toner resin and at least one colorant; and (b) blending sufficient surface additive particles and the toner particles in a high intensity blender for less than 10 minutes such that the weight of surface additives that become attached to toner particles is greater than three (3) percent of the weight of the classified particles wherein the blending is intense enough to yield Additive Adhesion Force Distribution (AAFD) percent values after 6 kJ of sonification energy greater than 25 percent.
- 10. The improved process of claim 9, wherein the step of forming further comprises:(a) mixing a toner resin and a colorant; (b) extruding the resin and colorant mixture; (c) attriting the resin and colorant mixture; and (d) classifying the attrited particles into particles averaging 4 to 10 microns in size.
- 11. The improved process of claim 9, wherein the step of forming further comprises forming the toner particles using an emulsion/aggregation/coalescence process.
