<p>A method of and apparatus for forming a multi-colour image, in which coloured toner powder is used to form colour separation images in the secondary colours magenta, cyan and yellow and also in one of the primary colours red, green or blue. Out of the separation images formed in the secondary colours, there are formed with transparent toner powder at least so many that the two primary colours not formed as separate separation image are represented therein. Preferably, blue is used as he primary colour and the yellow separation image is formed with transparent toner powder. Thus the method affords the possibility of forming multi-colour images by means of combinations of transparent and non-transparent toner powders. Preferably, the method is performed by combining on an intermediate support those separation images formed with toner powder not requiring to be transparent and then transferring them to an image receiving material and subsequently transferring to the image receiving material those separation images which are required to be formed with transparent toner powder.</p> |
