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： The present disclosure provides processes for reducing the particle size of latex resins and toners produced with such resins. In embodiments, a carboxylic acid may be added to materials utilized to produce a latex and reduce the particle size of the resulting latex particles and toner particles. In accordance with the present disclosure, one may be able to utilize materials for the production of latex resins and toners which may otherwise produce particles that are too large in the absence of the carboxylic acid.

摘要： A method of forming toner particles having surface particles attached thereto includes the steps of aggregating a material of at least one binder material and at least one colorant to produce toner particles, following aggregation, forming a mixture of the surface particles and the toner particles, and subjecting the mixture to a temperature above the glass transition temperature of the toner particles to coalesce the toner particles, whereby the surface particles become at least partially embedded within the surface of the toner particles. Toner particles prepared by such method include a core comprised of at least one binder and at least one colorant, and surface particles at an external surface of the toner particles, wherein at least about 50% of the surface particles are substantially completely covered by a portion of binder and a majority of the surface particles protrude from the toner particle surface a distance of at least 50% of the average particle size of the surface particles.
