Abstract: The invention relates to color toner compositions prepared from an aqueous pigment concentrate dispersion which renders a toner exhibiting improved pigment dispersion, and consequently improved image density and color characteristics.

Abstract: The invention relates to a commercially useful color thermal transfer dye sublimation toner comprising at least a binder resin and a sublimation dye component, the binder resin comprising a high molecular weight polymer having a molecular weight of above about 75,000, and a temperature, T1, of at least about 160° C. at which the viscosity is equal to 1×103, and the sublimation dye comprising a dye which sublimes at elevated temperatures above about 100° C. The invention further defines a process for the use of the toner.

Abstract: The invention relates to a commercially useful color thermal transfer dye sublimation toner comprising at least a binder resin and a sublimation dye component, the binder resin comprising a high molecular weight polymer having a molecular weight of above about 100,000, and the sublimation dye comprising a dye which sublimes at elevated temperatures above about 100.degree. C. The invention further defines a process for the use of the toner.

Abstract: The invention relates to a color toner composition comprising at least a binder resin and a colorant, and further comprising at least two charge control agents, wherein at least one of said charge control agents is a boron-containing compound, and at least two post-additive compounds used to treat the surface of said color toner.

Abstract: The present invention relates to apparatus for dispensing toner comprising a generally cylindrical container for containing a quantity of toner, at least one end aperture and at least one toner discharge opening formed therein, a first closure detachably, rotatably and sealingly secured to the cylindrical container for closing the end aperture, a shutter member extending from the first closure for selectively opening and closing the toner discharge opening of the cylindrical container when the first closure is rotated, and means for aligning the dispensing apparatus.

Abstract: A toner dispensing cartridge having a hollow toner cup with an open end portion to which a sleeve-cap is fitted. The sleeve-cap has at least one opening forming a mouth portion. The sleeve-cap is rotatable relative to the hollow toner cup. An agitator element disposed within the hollow toner cup, is connected to and rotatable by the sleeve-cap. With the hollow toner cup stationary, rotation of the sleeve-cap causes the agitator element to displace toner contained within the cartridge toward the mouth portion of the cartridge for egress of the toner through the mouth portion to toner receiving apparatus.
