    摘要： This invention provides a magnetic printer which permits substantially thorough removal of the residual developing agent from the magnetic latent image carrier or the photoreceptor's surface after the stage of image transfer even when the developing agent in use has high specific resistance and excels in both transfer property and developing property.The magnetic printer according to this invention is adapted to effect removal of any developing agent remaining on the magnetic latent image carrier after transfer of a visible image of developing agent by conferring electric charge upon the residual developing agent and subsequently forcing thorough departure of the residual developing agent from the magnetic latent image carrier by virtue of electrostatic force, wherein a source of electric pulses is used to generate the aforementioned electro-static force in such a manner that the electric charges imparted in advance to the residual developing agent are prevented from being reduced, totally eliminated or even reversed the polarity thereof by the DC electric field produced by the DC electric field produced between a bias roll and an opposite roll.

    摘要： Magnetic recording arrangement, for example, in a thermomagnetographic plain-paper printer, produces a latent magnetic image on a magnetic recording medium which is composed of a ferromagnetic layer, first magnetized along a predetermined direction before forming the latent magnetic image, and a magnetic layer of high permeability to be converted into a paramagnetic layer by being subjected to the heat from a heating head until the layer is heated to its Curie point or above. The magnetic layers are respectively laminated to opposite sides of a base layer, the heating head being placed at the opposite side of the base layer from the ferromagnetic layer so as to remain out of contact with the ferromagnetic layer, thus making the cleaning of the heating head substantially unnecessary while keeping the latent magnetic image of high quality. In the magnetic recording medium, a direct-current magnetic field of the opposite sense as the magnetized direction of the ferromagnetic layer, or an alternating-current magnetic field the phase of which is reversed at positions corresponding to opposite ends of at least a paramagnetized part, is applied to the paramagnetized part of the high permeable magnetic layer thus forming a magnetic latent image on the ferromagnetic layer by leakage of the magnetic flux from the paramagnetized part to the ferromagnetic layer.

    摘要： A thermomagnetic printer includes a recording unit for storing a latent image in which there are provided a magnetic recording layer providing thermomagnetic effect when placed in magnetic field with temperature graduation on one side of a photoconductive layer and a transparent electrically conductive layer on the other side.When storing a latent image in the magnetic recording layer, light which emits corresponding to the image to be reproduced on a paper is irradiated onto the photoconductive layer through the transparent electrically conductive layer while applying magnetic field to the magnetic recording layer and supplying electricity between the magnetic recording layer and the electrically conductive layer, whereby irradiated part of the photoconductive layer and the corresponding part of the magnetic recording layer are heated by Joule heat effect and the latter is magnetized by the thermomagnetic effect. By repeating the above operation in accordance with the image information, the latent image is formed in the magnetic recording layer.
