Abstract
A copying system and apparatus wherein a first electrostatic image of an original is formed and developed on a first photoconductive surface, and second electrostatic images of the developed image are repeatedly formed on a second photoconductive surface by illumination of the first surface. The second images, which can be formed at high speed, are developed and transferred to copy material.
Claims19
A copying system comprising in combination a first, memory, photoconductive surface, means to form and develop an electrostatic image of an original on said first, memory, photoconductive surface, a second photoconductive surface, positioned adjacent said first photoconductive surface means repeatedly forming on said second photoconductive surface second electrostatic images of the developed image on the first surface by illumination of the first surface, said second electrostatic images being identical with each other and corresponding to the first electrostatic image, means to transfer the second images from the second surface to copy material, and means to develop said second images.
A method of producing copies of an original by forming and developing an electrostatic image of the original on a first, memory, photoconductive surface, repeatedly forming on a second photoconductive surface positioned adjacent said first photoconductive surface, second electrostatic images of the developed image on the first surface by illumination of the first surface, said second electrostatic images being identical with each other and corresponding to the first electrostatic image, transferring the second images from the second surface to copy material and developing the second images.
