Abstract (en)
[origin: WO0232679A1] An image forming apparatus and a method for direct printing in which an image information is converted into a pattern of electrostatic fields for modulating a transport of charged toner particles from a particle carrier towards an image receiving surface. A printhead structure is arranged in the background electric field, including a plurality of apertures and control electrodes arranged in conjunction to the apertures. A plurality of the printhead structures (3005', 3005", 3005"', 3005"") and the particle carriers (3033', 3033", 3033"', 3033"") are arranged in a succession along the image receiving surface (3001). Each printhead structure has a particle-emitting plane at a printing distance (li', li", li"', li"") from the image receiving surface (3001) for selectively permitting or restricting transport of charged toner particles of a specific color. The printing distance (li"") of a later printhead structure (3005"") is at least mu m larger than the printing distance (li') of an earlier printhead structure (3005') in the succession.
