NON-MAGNETIC SINGLE COMPONENT EMULSION/AGGREGATION TONER COMPOSITION

摘要

A toner composition with a novel surface additive package for developing images. The additive package includes sol-gel silica, a PDMS silica, an organic spacer such as PMMA and HMDS silica. The toner composition exhibits improved control of voltage, higher print density, lower toner amount remaining on the roll, lower toner usage, and reduced drum contamination. The toner composition also exhibits improved dry rheological properties. These improved properties make this toner composition useful for higher speed printing while using less toner.
