Abstract
1474748 Electrophotography XEROX CORP 17 Sept 1974 [18 Sept 1973] 40550/74 Heading G2H An electro-photographic copier incorporates a filter apparatus and a plurality of developing means, the filter apparatus and developing means being so inter-connected that the copier can alternatively be used to produce a mono-chromatic image of the whole of an original with black toner and a series of coloured images of a filtered colour, derivatives of the original, made with toner of colours com- - plementary to those of the filters, the developing means each being movably mounted, with a resilient bias keeping it out of its operating position until it is required.
