A carrier comprised of a core and a polymer generated from a mixture of two latexes, and wherein the first latex enables a polymer with a high molecular weight, and the second latex enables a polymer with a low molecular weight, and wherein high represents a weight average molecular weight of from about 1,000,000 to about 8,000,000, and said low represents a weight average molecular weight of from about 500,000 to about 750,000.
摘要:
A method of forming toner particles having surface particles attached thereto includes the steps of aggregating a material of at least one binder material and at least one colorant to produce toner particles, following aggregation, forming a mixture of the surface particles and the toner particles, and subjecting the mixture to a temperature above the glass transition temperature of the toner particles to coalesce the toner particles, whereby the surface particles become at least partially embedded within the surface of the toner particles. Toner particles prepared by such method include a core comprised of at least one binder and at least one colorant, and surface particles at an external surface of the toner particles, wherein at least about 50% of the surface particles are substantially completely covered by a portion of binder and a majority of the surface particles protrude from the toner particle surface a distance of at least 50% of the average particle size of the surface particles.
摘要:
The present disclosure provides toners and methods for their production. In embodiments, the amount of coagulant utilized in producing those toners may be less than amounts currently in use, which may have a beneficial effect by reducing the time for coalescence. Modified waxes may also be utilized which provide excellent gloss and charging characteristics.
