Abstract

1496815 Electro-photography XEROX CORP 27 March 1975 [29 March 1974] 12944/75 Heading G2H When an original is to be copied with parts distinguished in a second colour, according to a pattern not present in the original, the parts to be distinguished are identified by markers 72, and the photo-conductive drum 10 of the copier is rotated once for the main colour, and once for each additional colour. Switches 82 are actuated by magnets 80 on the markers during exposure, and actuate light source 28 to erase the latent image of the part to be distinguished during one revolution and, after development, transfer and production of a second latent image, all but the part to be distinguished during another. The partial images are developed with appropriate tones, so that a copy sheet receives a succession of non-overlapping partial developed images in different colours, and displays them as a multi-coloured copy.
