This invention is directed to positively charged toners comprised of a resin, a colorant, and an additive possessing an anion, and more specifically, an alkyl pyridinium compound and its corresponding hydrate, of the formulas ##STR1## wherein A is an anion, which in a preferred embodiment is selected from halides such as fluoride, chloride, bromide, or iodide; sulfate, sulfonate, nitrate borate, and phosphate; R is a hydrocarbon radical containing from about 8 to about 22 carbon atoms and preferably from 12 to 18 carbon atoms. An important embodiment of the present invention is directed to a process for rapidly charging (or admixing) uncharged dry electrostatographic toner, containing the alkyl pyridinium compounds of the above formulas, subsequent to its addition to previously charged developer, whereby the uncharged toner particles acquire a charge within a period of from about 1 minute to about 5 minutes. The toners of this invention are useful for developing images of high quality in an electrostatographic imaging system.
