摘要:
Toners including a low melt wax and a carnauba wax are described. The toners include at least one binder, at least one colorant, at least one wax having a melting point of 135° C. or less, and a compatibilizer wax (e.g., carnauba wax). The low melt wax is preferably polyethylene wax. Images may be formed with the toners in an image forming process including steps of depositing the toner onto a latent image of an imaging member to form a toner image, transferring the toner image to an image receiving substrate, and fusing the toner image. During the fusing, the at least one wax and the compatibilizer wax exude from the toner, forming a stripping enhancing layer upon the toner image. Thus, fuser roll stripping performance is enhanced.

A developer composition comprising a magnetic toner and a mixture comprised of bare carrier core particles free of a coating and coated carrier particles, and wherein said bare carrier core particles are present in an amount of from about 50 weight percent to about 90 weight percent, and said coated carrier particles are present in an amount of from about 50 weight percent to about 90 weight percent, and wherein the total thereof is about 100 percent.
摘要:
Magnetic toner compositions, conductive developer compositions, and methods for producing images in a hybrid jumping development system, more specifically, in a magnetic ink character recognition system, are disclosed. The developer compositions contain coated magnetic toner particles and coated carrier particles. The toner compositions include a resin, colorant, wax, magnetic component, and surface additives of coated silica, titania, and zinc stearate.

Included is an emulsion aggregation toner formulation having at least one latex and a combination of at least two waxes, wherein one wax is a synthetic wax, and another wax is a natural wax, and further including a developer containing a carrier and the just-described toner.
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.
