ABSTRACT:
Toner particles comprising a polyester binder and a charge control agent are provided wherein such agent is a quaternary ammonium salt having one or more ester-containing moieties. Such an ester-containing salt causes toner particles to display lower fusing temperature, improved paper adhesion indexes, and improved polyester binder compatibility compared to nonesterified salts.
