Description

ABSTRACT:
A first and second electrode web, of which at least one is transparent, are transported along respective paths both passing through an exposure station. A toner applicator upstream of the exposure station applies to the first web a uniform layer of toner suspension. Upstream of the exposure station, the coated first web and the second web are sandwiched to form a sandwiched film pack in which the toner suspension layer is located intermediate the two webs. The transport of at least that section of the webs constituting the sandwiched film pack at the exposure station is intermittent, but nevertheless the relative movement between the toner applicator and the first web is maintained uninterruptedly unidirectional and of uninterruptedly constant speed. At the exposure station, a color toner image is formed, on a whole-image basis, by projecting the whole image to be copied onto the toner suspension layer of the film pack section through the transparent web thereof while such section is at a standstill at the exposure station, and a corresponding color toner image is produced photoelectrophoretically. Downstream of the exposure station, the color toner image is transferred onto copy material.
