Abstract

1495429 Developing electrostatic images ITEK CORP 23 April 1975 [24 June 1974] 16750/75 Heading G2H In an electro-photographic copying apparatus, the latent image is cascade developed a pre-set number of times, e.g. 2, 3 or 4 times, before it is transferred to a copy sheet so that large solid or half tone areas of the image may be fully developed.
