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.

摘要： A black toner of toner particles including at least one binder, at least one black colorant, and a package of external additives is described, wherein the at least one binder includes a styrene acrylate binder and wherein the external additives include each of a first silica having an average particle size of from about 35 to about 45 nm, a second silica having an average particle size of from about 135 to about 160 nm, and a titania having an average particle size of from about 35 to about 45 nm. Also described is a developer that includes the black toner and carrier particles comprising a core of ferrite coated with a coating comprising a polymethyl methacrylate polymer and fluoro-copolymer, carbon black and melamine beads. The black toner and developer are preferably used in a semiconductive magnetic brush development system.
