Abstract
An image-forming device for recording images on a dielectric surface of an image-recording medium, in which the dielectric surface is in contact, in an image-forming zone, with developing powder bound to a powder support by a magnet system, the magnet system having two oppositely magnetized areas separated by a gap and, as considered in the direction of transport of the image-recording medium, disposed consecutively, the distance between at least one of the magnetized areas and the surface of the powder support being less than 150 .mu.m and the distance between the same magnetized area and the surface of the image-recording medium being less than 600 .mu.m, thus raising the background-free level while less magnetic material is required for the magnet system than in comparable devices.
