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 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.

摘要:
A toner composition including toner particles that have a resin, an optional wax, and an optional colorant; and a surface additive at least partially coating toner particle surfaces. The surface additive includes a mixture of a hexamethyldisilazane (HMDS) surface treated silica, a sol-gel silica that is not surface treated, and a polydimethylsiloxane (PDMS) surface treated silica.
摘要:
Emulsion aggregation toner particles comprising at least one binder resin and a colorant, wherein the colorant comprises at least one ceramic pigment.
摘要:
Toner particles include a shell and a core, wherein the shell includes charge control agent-treated spacer particles that cause protrusions from the toner particle surface.
