Abstract
An improved liquid toner composition for developing latent electrostatic images comprising toner particles, a release agent and a nonpolar dispersant liquid. An agent causing an apparent increase in the cohesivity of the toner particles may be included in the toner composition, or such agent may be used independently of the release agent in the toner composition.
