    摘要: The present disclosure relates to a magnetic toner composition. The toner composition includes one or more resins, and spherical ferromagnetic nanoparticles. Also provided is a process for preparing these toners including ferromagnetic nanoparticles. In embodiments, the aggregation of the toner is conducted at a pH greater than about 7, without the use of a coagulant. Additionally, in embodiments, freezing (stopping particle growth) and coalescence of the toner particles may be conducted at a pH greater than about 9. In yet other embodiments, the process may be conducted under an inert gas such as argon to avoid oxidation of the ferromagnetic nanoparticles during toner preparation.

    摘要: Toner particles are provided which may, in embodiments, include a core and a shell formed in situ. The resins utilized to form the core, the shell, or both, may be contacted with a water soluble initiator. The resin, in embodiments present in the shell, cross-links at a temperature near the temperature for coalescence, and may prevent a crystalline resin in the core from migrating to the toner surface.
