Abstract
The invention relates to a process for the preparation of a dry toner powder containing a wax component and formed using a limited coalescence suspension polymerization process. Both conventional and aqueous dispersed waxes may be used to form the toner particles. Likewise, both dry and aqueous dispersed pigments may be used. The resulting toner provides properties desired in the next generation of toners including small uniform particle size as well as desirable anti-blocking and high-temperature anti-offset properties.
