ABSTRACT:
A method and ink composition for development of an electrostatic latent image with liquid developer is disclosed. The liquid developer has a viscosity suitable for convenient application to an imaged surface in the development of latent electrostatic images and has improved conductivity resulting from incorporating conductivity control agents in the form of quaternary ammonium compounds which are soluble in the carrier of the ink composition. The conductive ink composition comprises a coloring agent, optionally a binder and a dispersing agent, a carrier and a quaternary ammonium compound soluble in the liquid carrier.
