Abstract
A solvation-based method for charging toner particles in a liquid electrophotographic developer composition is provided. The method makes use of a material containing specific salvation sites which are incorporated into the resinous phase of the toner, and a charge director which is a metal salt, the metal, cationic component of which is effective to form a highly stable, 'solvated' charged toner complex. Toner and developer compositions are also provided which make use of the novel solvation-based mode of charge direction.
