ADDITION OF EXTRA PARTICULATE ADDITIVES TO CHEMICALLY PROCESSED TONER

摘要

The present invention relates to the combination of a chemically processed toner with extra particulate additive in a conical mixer. The toner may include polymer resins having a glass transition temperature (Tg) wherein the mixer and/or toner may be maintained below the glass transition temperature during mixing. Prior to mixing the toner particles may also be de-agglomerated or mechanically agitated.
