Summary:A liquid toner having a mineral oil vehicle, a blend of Surlyn ionomeric resin and Nucrel resin, pigment and, as charge director, lecithin, N-methyl-2-pyrrolidone and calcium Petronate. The charge director optimizes speed of recovery of charge properties during continual use. The mineral oil does not vaporize well and is readily condensed, thus permitting use as a confined toner.
