  • Toner and developer for magnetic brush development system
    Patent number: 6416916
    Abstract: A toner of toner particles containing at least one binder, at least one color ant, and an external additive package comprised of zinc stearate and at. least one of silicon dioxide or titanium dioxide, wherein the amount of zinc stearate is limited to about 0.10 percent by weight or less of the toner. It has been surprisingly found that when the amount of zinc stearate is so limited, a developer formed from the toner exhibits excellent triboelectric charging and stability and excellent developer flow. When the developer is used in a magnetic brush development system, consistent, high quality copy images are formed substantially without any depletion defects over time.
