Abstract

1282991 Electro-photographic developing apparatus XEROX CORP 9 March 1970 [10 March 1969] 11097/70 Heading G2H An electrostatic latent image, formed on a web 26 by a stylus 22, is developed by toner applied by a rotating brush 21 from a moving web 10. Application of toner to brush 21 is controlled by an electrode 19 which contacts a conductive backing e.g. aluminium of web 10, the web having a layer e.g. of felt, paper, plastics, or fibre glass for supporting toner. Brush 21 may be camel's hair, rabbit's fur or nylon.
