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.
