摘要: Toner including toner particles having a calcium-containing material at least in a surface portion of the toner particle, wherein the toner particles contain calcium in an amount of from 20 ppm to about 300 ppm of calcium by dry weight of the toner. Developer including a carrier and a toner, wherein the toner includes toner particles having a calcium-containing material at least in a surface portion of the toner particles. In an emulsion aggregation process for making toner particles, the toner particles are treated with calcium. The addition of calcium to the toner particles improves toner performance by lowering cohesion and charging, thereby generating an image of high gloss.

摘要: Low fix temperature toners are fabricated by a two step melt mixing and reactive melt mixing process wherein there is initially prepared, for example, using a melt mixing device, a composite of pigment and resin, followed by crosslinking of the resin component at high temperature and high shear to produce a partially crosslinked toner with substantially no unpigmented gel domains. The toners are particularly suitable for high speed fusing, show excellent offset resistance and wide fusing latitude, and superior vinyl offset properties.

摘要: A process for the preparation of encapsulated toners which comprises blending core momomer or monomers, free radical initiator, pigment, and an oil soluble shell monomer; dispersing the resulting mixture in a stabilized aqueous suspension; thereafter subjecting the stabilized droplets to a shell forming interfacial polycondensation reaction by adding a water soluble shell monomer or monomers; subsequently forming the core resin binder by heat induced free radical polymerization within the newly formed capsules; washing the toner suspension; subsequently removing water therefrom in a fluidized bed dryer to obtain a dry encapsulated toner with a surface moisture content of about 0.3 percent by weight to about 0.8 percent by weight; and thereafter blending the encapsulated toner with surface additives.
