  • Toner compositions and developers containing such toners
    Patent number: 8592115
    Abstract: 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 two HMDS silicas. 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 and improved fix properties. These improved properties make this toner composition useful for higher speed printing while using less toner.
    Type: Grant
