    摘要: A method for imaging a printing form in which the printing form is charged on its entire surface and is coated on its entire surface with particles, in particular toner particles, which bear the opposite charge. The layer formed by the particles is then fixed in accordance with the image by a beam, in particular a laser beam, and especially by infrared radiation, on the surface of the printing form or ablated in accordance with the image. Thereupon, the unfixed portions of the layer are removed or the non-ablated portions are fixed by full-surface heat treatment.

    摘要: An image development method and apparatus, wherein a support member is provided with a layer of marking material thereon, and an electrostatic latent image is created in the layer of marking material via image-wise charging of the layer of marking material. A selectively controllable charging device for directing a charge stream toward the support member having the layer of marking material coated thereon. The image-wise charge stream corresponds to the latent image, which, in turn, leads to image-wise charging of the toner layer, such that the toner layer itself becomes the latent image carrier. The latent image carrying toner layer is subsequently developed and transferred to a copy substrate to produce an output document.

    摘要: A dry-type toner is temporarily put on a printing paper with electrification by an electrifying unit and a toner supplying unit. A laser diode is driven on the basis of a video signal to emit a laser beam by which the dry-type toner put on the printing paper is melted and fixed thereon. A remaining toner that was not melted on the printing paper is eliminated by a cleaning unit. A printing by the laser beam can be realized most easily without using expensive parts such as a photosensitive material or the like and without increasing its mechanism and circuit scale. A printing apparatus includes a body circuit (4) for producing a driving signal on the basis of a video signal, an electrifying unit (10) and a toner supplying unit (11) for temporarily putting a dry-type toner on a printing paper (5) with electrification, a laser diode (3) being driven by the driving signal from the body circuit (4) to emit a laser beam to melt the dry-type toner put on the printing paper (5) with electrification by the electrifying unit (10) and the toner supplying unit (11) so that the dry-type toner thus melted is fixed on the printing paper (5) and a cleaning unit (9) for eliminating a remaining toner that is not melted on the printing paper (5).

    摘要: A migration imaging system using a laser-addressable thermoplastic imaging member. The imaging member comprises a supporting section and a thermoplastic imaging surface layer. A charged, uniform layer of marking particles is deposited on the imaging surface layer. An imagewise-modulated laser beam transforms selected volumes of the imaging surface layer in an imagewise pattern to a permeable state. Charged marking particles that superpose a transformed volume then migrate into the imaging surface layer so as to be retained. Unaddressed marking particles are cleaned away. The imaging member, or solely the imaging surface layer, may be transferred and bonded to a receiver such as a drum for use as an exposure mask, or to a receiver sheet to provide a hard copy reproduction. The processed imaging member is usable as a master in a xeroprinting system.

    摘要: A method of producing electrostatic images in a machine using pre-cut or continuous paper, in which a coloured photoconductive medium is applied to the surface of the sheet and charged and then exposed to electro-magnetic waves to produce a latent image on the photoconductor film by discharging the photoconductor in non-image areas and selectively removing the photoconductor film from the non-image areas to leave a visible image on plain paper in the image areas only.
