Abstract

Disclosed are improved positively charged electrostatic toner compositions comprised of a polyblend mixture of a crosslinked copolymer composition, and a second polymer, pigment particles, a wax component of a molecular weight of from 500 to about 20,000, and a charge enhancing additive. These compositions are particularly useful in imaging systems wherein release oils, such as silicone, are not required.
