Abstract
Abstract A latent image formed in a photoconductor surface carried on a conductive base is transferred to a sheet of untreated paper by placing said sheet in contact with said surface and imposing a high-voltage potential between the sheet and base. A charge image is thus formed in the sheet of paper corresponding to the latent image in the photoconductor surface, and this charge image is thereafter developed. These lenses are rotatably mounted such that the lenses rotate successively into the optical path for transmitting the image being scanned to the photoconductive surface.
