摘要： A radiation unit for a fixation device for fixation of toner material on a printing stock surface for an electrophotographic printing machine, as well as a method for exposure and fixation of toner material on a printing stock surface. Exposure for fixation of toner material occurs essentially indirectly, i.e., the light emitted by the radiation unit is reflected at least once, so that high uniformity and homogeneity of the radiation, efficient energy utilization and avoidance of adverse changes on the printing stock are achieved. A high-energy density, low housing dimensions and independence of the radiation from the employed printing unit are achieved by the fact that the radiation wavelength lies essentially in the ultraviolet spectral range.

摘要： A method of developing electrostatic images with a two component developer avoids the break-in period of developer by providing a fresh mixture of carrier and toner, which toner has a first particle size but replenishes the mixture in use with toner having a second particle size larger than the first particle size. This compensates for the tendency of electrostatic images to preferentially attract the larger particles in a toner mixture.

摘要： The invention provides a mixture of coated carrier particles suitable for use in dry electrographic developer wherein each of the types of carrier particles occupies a position in the triboelectric continuum different from the position of the other type and the level of charge to which the mixture of carrier particles charges the toner in a developer continuously increases or decreases between a high level in which said mixture comprises all of one type of carrier particles to a low level in which said mixture comprises all of the other type of carrier particles.This type of carrier provides a simple way to adjust the charge on the toner provided by the carrier, that is, more of one of the types of carrier particles in the mixture can be added to the toner to either increase or decrease the charge on the toner.

摘要： To create an overcoat on a toner image, a clear heat softenable particulate material is applied to a fusing surface before the fusing surface contacts the toner image in a fusing nip. The particulate material softens in the fusing process and ends up as a clear overcoat for the toner image, protecting it from scratches, fingerprints, deglossing and/or softening from heat.

摘要： A method is described for the preparation of electrostatographic toner particles which involves the surface treatment of a pigment by depositing thereon a coating of an elastomeric thermoplastic polymer. The method involves preparing a polymer solution by dissolving an elastomeric thermoplastic polymer selected from the group consisting of linear styrene-isoprene-styrene triblock copolymers, linear styrene-ethylene-butylene-styrene triblock copolymers, linear styrene-isoprene diblock copolymers and linear styrene-ethylene-propylene diblock copolymers in a first solvent capable of dissolving the polymer at ambient temperature; forming a pigment dispersion by mixing at ambient temperature a pigment, a first polymer material and a second solvent in which the elastomeric thermoplastic polymer is insoluble at ambient temperature; admixing the polymer solution with the pigment dispersion so resulting in the elastomeric thermoplastic polymer precipitating out upon the surface of the pigment; mixing the elastomeric thermoplastic polymer coated pigment dispersion thus formed with a solvent in which the elastomeric thermoplastic polymer is insoluble at ambient temperature and, optionally, a second polymer material and, optionally, a charge-control agent to form an organic phase; dispersing the organic phase in an aqueous phase comprising a particulate stabilizer and, optionally, a promoter; homogenizing the resultant mixture, and evaporating the solvent and washing and drying the resultant product.
