Abstract

1528767 Electrophotography COULTER SYSTEMS CORP 22 Oct 1975 [23 Oct 1974] 43404/75 Heading B6C An imaged electrophotographic member is repeatedly developed, and the resulting toner images are transferred to copy material, all in the absence of ambient light, or any transferassisting field, to give a plurality of copies from one electrostatic latent image. Preferably the member used has an ability to hold charge at or below its surface, rather than on its surface. Copies may be made until their density falls below an acceptable standard.
