Abstract: Wax dispersion and domain size can be effectively controlled by incorporating a small amount of a hybrid resin binder and or a wax compatibilizer in the toner formulation. Such toners show smaller wax domain size and improved fusing offset window, fusegrade and filming resistance, and therefore improved print quality and reliability. The hybrid resin contains a polyester unit via condensation reaction and a vinyl-based polymer unit via radical polymerization. The hybrid resin is highly compatible with the polyester resin binder, and at same time, can well accommodate low molecular weight polyolefin waxes in the vinyl polymer entity enabling a desirable smaller wax domain size. The wax compatibilizer is a thermoplastic styrenic block copolymer.

Abstract: The present invention relates to controlling the mass flow of toner in an image forming device or a toner cartridge. The toner composition includes extra particulate additives including a conductive additive. The extra particulate additives may also include relatively small silica particles or relatively large silica.

Abstract: The present invention relates to the use of extra particulate additives in selected chemically processed toner compositions for use in an image forming apparatus. The extra particulate additive may have a controlled aspect ratio and be combined with the chemically processed toner. The chemically processed toner may provide toner particles having controlled diameters and rheological properties that may be combined with a release agent. The release agent may also be selected with respect to, e.g., concentration and/or mean domain size within the toner particles including considerations of coating chemistry and/or DSC melting behavior.

Abstract: A functionalized copolymer containing a main chain derived from polymerizable monomers and pendent functional groups terminated with one or more ? or ? ethylenically or acetylenically unsaturated groups. The functionalized copolymers are self cross-linking and are suitable for use as binders.

Abstract: A conductive elastomeric foam composite is presented, comprising an elastomer foam and polypyrrole, thiophene, or aniline and derivatives thereof. The foam is manufactured by first diffusing an oxidant into the dense polymer phase of a solvent-swollen foam and then diffusing pyrrole or pyrrole derivative vapor or solution into the dried foam, resulting in an in situ chemical oxidative polymerization of pyrrole at the oxidant site. Only about 5 wt % of conductive polymer is required for observing an insulator to conductor transition. The conductivity of the composite foam can be effectively controlled between 10−7 and 10−1 S/cm by varying either the amount of oxidant used and/or the copolymer composition.
