ABSTRACT:
Electrostatographic reproducing apparatus comprising a reusable electrostatographic imaging web having an insulating imaging surface positioned between a web supply roll and a web take up roll each roll being fastened to the end of the web. The web is provided with means to form an electrostatic latent image on the web and develop said image with a toner image. The image is formed and developed upon the passage of the web from the supply roll to the take up roll, where the web with the toner image thereon is brought into contact with a copy sheet and wound around the take up roll during the first cycle of a two cycle imaging process. During the second cycle of the imaging process the web is unwound from the take up roll and rewound on the supply roll with the toner image being transferred to the copy substrate, separated from the imaging web, with the web being fully rewound on the web supply roll. In the specific embodiment the web comprises a photoconductive insulating layer which is positively driven from the supply roll in both the supply roll unwind and rewind directions and tension is maintained within the web by means of a spring in the web take up roll. Furthermore, the circumference of the take up roll is at least equal to the length of the developed image on the web.
