Liquid ink transfer system

An electrophotographic printing machine of the type having an electrostatic latent image recorded on a photoconductive surface developed with a liquid developer material to form a liquid image thereon, wherein the liquid image is transferred from the photoconductive surface to a substantially electrically non-conductive, flexible copy sheet with the liquid image being charged to one polarity and the photoconductive surface being charged to a polarity opposite to the polarity of the charge of the liquid image, including:

• first means for applying a first charge on the copy sheet with the first charge on the copy sheet being of the same polarity as the polarity of the charge of the liquid image to cause the copy sheet to adhere releasably to the photoconductive surface with the liquid image being interposed therebetween;
• and
• second means for applying a second charge on the copy sheet after the first charge has been applied thereon with the second charge on the copy sheet being of an opposite polarity to the polarity of the charge of the liquid image to cause the liquid image to be attracted to the copy sheet.
