Abstract

An induction imaging method and apparatus which avoids air breakdown problems is disclosed. The imaging method comprises first providing, a. photoconductive surface 10 with an electross. static latent image 12 thereon. A dielectric web 11 is positioned against the photoconductive surface and a corona device 18, preferably a DC biased AC corOtron, is used to induce the elect├žostatic latent image. Onto the web. The web is positioned in intimate contact with the surface .and a first conductive roller 20 and separated from the photoconductive surface onto the firSt roller. The first roller is biased at a potential sufficient to prevent charge trsnqfer from the sure face to the web. The web is then positioned in intimate con-tact with the first roller and a second conductive ├žoller 20A, and separated from the first roller onto the second roller. The second roller is also biased at a potential sufficient to prevent charge transfer from the first roller 20 to web 11. Thereafter, the electrostatic image formed on the web is de-r veloped by a liquid developing systel wherein the web is first positioned in intimate contact with second roller 204 and is developed by a biased gravure development rolLer 20. The de-veloped image is then transferred from the Web . to' a receiving member 21.
