Abstract (en)
An electrostatographic printing apparatus is provided, suited for single-pass sequential multi-colour duplex printing, characterized in that the printing proceeds by depositing and fixing toner particles on a final substrate (1) in web form and the apparatus comprises : 1) two printing systems, a first (I) and a second (11) one, being arranged in succession at opposite sides of the final substrate (1), each of the printing systems comprising an intermediate rotatable toner-receiving member (3), 2) means, in each of the printing systems, for rotationally driving the intermediate toner-receiving member (3), 3) means, in each of the printing systems, for superimposing colour separation images in registration on the intermediate toner-receiving member (3), and 4) means, in each of the printing systems, for simultaneously transferring the superposed toner image from the toner-receiving member (3) onto the final substrate (1), the transferring means being a drum or roller (4) optionally electrically biased and forming with the intermediate toner-receiving member (3) a nip through which the final substrate (1) is passed in synchronism with the peripheral movement of the toner-receiving member (3). In a preferred embodiment of the invention, the colour separation images are applied in registration to said intermediate toner-receiving member by a plurality of rotatable image-producing electrostatographic drums. <IMAGE>
