Abstract
An electrostatic latent image residing on an electrically insulating surface used to induce a similar image on a sectionally conductive member by bringing one surface of the sectionally conductive member into proximity with the latent image while the opposite surface of the sectionally conductive member is brought to ground potential. The sectionally conductive member is then removed from proximity with the latent image. To prevent electrical breakdown during removal, a grounded electrode is placed adjacent the surface of the sectionally conductive member opposite the latent image but separated from the sectionally conductive member by a thin electrically insulating layer. A latent image is thus formed on the sectionally conductive member which can be developed by conventional means such as with electroscopic materials well known in the xerographic art.
