Copier having simultaneous two-colour copier operation mode

摘要

An electrophotographic copier (K) having three or more developing units (4 to 6) which in each case contain developer in a different colour and are arranged along a photo-sensitive element (1) and serve to develop a latent picture (image) which has been generated on the photosensitive element (1) by exposing a picture of an original so that a multicoloured image is obtained, having a selecting element (306) for selecting any two developer units (4 to 6), a device (100) for marking regions (A, B and C) of the latent picture to be developed by the two selected developing units, and a device (621 to 623) for subsequently actuating the two selected developing units as a function of the specified areas (A, B, and C) for producing a two-coloured picture during an exposure operation of the picture of the original. <IMAGE>
