Abstract

The present disclosure provides processes for producing toners by emulsion aggregation where the resulting toner particles have high pigment loadings and desired circularity. The methods include adding a metal, in embodiments a metal salt, at the beginning of coalescence, which surprisingly speeds the coalescence process and produces toner particles having a desired size and circularity for use in electrophotographic imaging systems.
