Abstract
Disclosed is a a toner composition comprising a resin, a colorant, and a charge control additive selected from the group consisting of (a) zinc 3,5-di-tert-butyl salicylate compounds; (b) mixtures of a zinc 3,5-di-tert-butyl salicylate compound and an alkyl pyridinium halide; (c) mixtures of a zinc 3,5-di-tert-butyl salicylate compound and distearyl dimethyl ammonium methyl sulfate; (d) mixtures of a zinc 3,5-di-tert-butyl salicylate compound and distearyl dimethyl ammonium bisulfate; (e) mixtures of an aluminum 3,5-di-tert-butyl salicylate compound and an alkyl pyridinium halide; (f) mixtures of an aluminum 3,5-di-tert-butyl salicylate compound and distearyl dimethyl ammonium methyl sulfate; (g) mixtures of an aluminum 3,5-di-tert-butyl salicylate compound and distearyl dimethyl ammonium bisulfate; and mixtures thereof, a colloidal silica external additive, and a metal salt of a fatty acid external additive. Also disclosed are imaging processes employing the toner, including a process for forming two-color images which comprises creating on an imaging member a latent image comprising areas of high, medium, and low potential, developing the low areas of potential with a developer comprises the toner disclosed herein and a carrier, subsequently developing the high areas of potential with a developer comprising a toner of a second color and a carrier, transferring the developed two-color image to a substrate, and optionally permanently affixing the image to the substrate.
