    摘要： A printing device, comprising a movable image-forming medium, with a support (43), the surface of which is formed by a dielectric layer (41), an image-forming station disposed along the trajectory of the image-forming medium and comprising a magnetic roller (40) having an electrically conductive non-magnetic outer sleeve (51) and magnets (48,49,50) disposed inside the sleeve (51), means for supplying electrically conductive toner to a linear zone (45) where the image formation takes place, and a number of electrodes ( 4 2) each of which can be actuated by a voltage source and each of which can generate an electric field across the dielectric layer (41) in the image-forming station over part of the zone (45) in which image formation takes place, the electric field corresponding to an image pattern required to be formed on the image-forming medium, in which the electrodes (42) are disposed so as to be insulated from one another and are covered by a dielectric layer (41) and extend in the direction of movement (52) of the image-forming medium.

    摘要： A method of forming a multi-colour image, comprising image ele­ments in a first colour which along at least part of their circum­ference adjoin image elements of a second and/or third and/or following colour, separation images in the first, second, third and any following colour being generated, which separation images are each built up from image dot patterns of coloured toner powder, said separation images being transferred to an intermediate support (1) to collect them there to form a multi-colour image and the multi-colour image being then transferred from the intermediate support (1) to an image receiving material, wherein the second and each following generated separation image is so generated that the image elements which on transfer onto the intermediate suppport (1) are required to adjoin image elements of a separation image already transferred thereto previously at least partially overlap said previously trans­ferred image elements, the transfer of the second and each following separation image to the intermediate support (1) is effected by pressing the element (7) which bears the separation image against the intermediate suppport (1) with a force of no more than 1000 N per linear metre and an intermediate support (1) is used which has a sur­face of resilient material.
    The effect of the method according to the invention is that the adverse effects of any register error between the separation images of the multi-colour image are completely or at least largely rendered invisible.
    The invention also relates to apparatus for performing the method.
