摘要

The electrophotographic properties of mono- and dual-component toners produced by the polymerization method, which is an in situ polymerization technique, were studied. The effects of different production methods were also described. For the dual-component type toner, the effects of different production methods for the fundamental particle properties were not observed, except for the powder fluidity. Enhancement of the fluidity was introduced by the spherical shape of the polymerized toner particles. The image quality with this toner was also enhanced in the reproduction of fine lines and small dots. The powder fluidity of the monocompo-nent polymerized toner was not improved over that of the conventional melt-mixed toner. The spherical particles of the polymerized toner may introduce a smooth and efficient agitation on the magnetic brush, so that the toner particles form a very uniform triboelectric charge. Accordingly, the developed toner image has a smooth profile with low background fog. The polymerization method can reduce the number of manufacturing processes involved in making small-particle toner. The main advantages come from cost reduction. It is shown that the polymerized toner has some desirable properties, which can enhance its potential for use as electrophotographic toner.
