摘要： The crystalline state of the release wax of an electrophotographic toner is made so that the crystalline state has the highest melt transition temperature. In an embodiment, this is done by synthesizing the toner particles at a controlled low temperature, the temperature being that found consistent with subsequent cooling to just the crystalline state of having the highest melt transition temperature. Chemically prepared toner by agglomeration is well suited to employing this. In such a system agglomerated particles are suspended in a liquid medium. The particles are then heated while so suspended to fuse the particles into a mixture constituting toner. That fusing is conducted at the foregoing controlled temperature.

摘要： 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.
