ABSTRACT:
This invention relates to improved positively charged toner compositions for use in developing electrostatic images contained in electrostatographic imaging devices wherein fusing is accomplished with a fuser roll fabricated from lead oxide and a vinylidene fluoride hexafluoropropylene copolymer, which composition is comprised of resin particles, pigment particles, and as the charge enhancing additive present in an amount of from about 0.1 percent by weight to about 10 percent by weight, a pyridinium tetrafluoroborate of the following formula: ##STR1## wherein R.sub.1 is an alkyl group containing from about 1 carbon atom to about 22 carbon atoms, and R.sub.2 is an alkyl group containing from about 1 carbon atom to about 8 carbon atoms, or a halogen, and n is zero or 1.
