ABSTRACT:
A toner composition includes toner particles having at least one spacer of substantially monodisperse latex particles that are dried and attached to the toner particles, in which the attached latex particles have an average particle size of from about 60 nm to about 500 nm. The presence of the spacer enables improved toner transfer efficiency maintainability while maintaining excellent tribo level, tribo stability with aging, charge through performance and cohesion behavior with aging.
