Positive toners containing alkyl picolinium compounds

摘要

Disclosed are positive toners comprised of a toner resin, a colorant, or pigment, and an alkyl picolinium compound selected from the group consisting of those represented by the following formula: wherein A is an anion which in a preferred embodiment is a halide such as chloride, bromide, or iodide, sulphate, sulphonate, phosphate and nitrate, and R is a hydrocarbon radical containing from 8 to 22 carbon atoms and preferably from about 12 to 18 carbon atoms. These toners when combined with carrier materials can be used as developers in electrophotographic systems.
