Abstract

1479377 Developing electrostatic images PENTACON DRESDEN KAMERA-UND KINOWERKE VEB 16 May 1975 [31 May 1974] 20878/75 Heading G2H Toner 8 is added to the developer mixture in chamber 1 by being forced through gap 11 by roller 9, the gap being shaped to lead into the chamber in the direction 6 in which the developer moves under the influence of paddle wheels 3, 4. Preferably the roller 9 has a soft, elastic coating, is a brush roller, with bristles which deflect against the lower wall of container 9 and straighten as they pass the gap 11, or has soft and elastic blades.
