Abstract
A method of transferring images from one surface to another, which, instead of using a steady field uses a corona to build up a charge on a roller which transfers the charge to the surface where transfer is required. The device comprises a pair of rollers which are urged toward each other, one of the rollers having an insulator surface, the other roller forming an electrode, the charge being applied to the insulator surface on the one roller by means of a corona generating device spaced from the insulator surface and remote from the electrode roller.
