ABSTRACT:
An apparatus in which a liquid image is transferred from a surface to a substantially electrically non-conductive, flexible copy sheet with the liquid image being charged to one polarity and the surface being charged to a polarity opposite to the polarity of the charge of the liquid image. A first charge is applied on the copy sheet. The first charge is of the same polarity as the polarity of the charge of the liquid image. This causes the copy sheet to adhere releasably to the surface with the liquid image being interposed therebetween. A second charge is applied on the copy sheet after the first charge has been applied thereon. The second charge is of an opposite polarity to the polarity of the charge of the liquid image. This causes the liquid image to be attracted to the copy sheet.
