Method of developing electrostatic latent images with conductive liquid developer

A method for the development of latent electrostatic images on a substrate comprising positioning close, but spaced from the electrostatic latent image on said substrate, a non-volatile, non-hydroscopic, conductive liquid developer comprising about 5-25 weight percent of a coloring agent, about 1-10 weight percent of a dispersing agent, but 5-30 weight percent of a resin binder and the balance triethylene glycol monobutyl ether;

• and applying said non-volatile conductive liquid developer to said substrate from flow aiding elements in physical contact between said liquid developer and said substrate by applying a bias to said liquid developer whereby said liquid developer moves along the flow aiding elements and thereby develops said electrostatic latent image.
