    Abstract: An image-forming apparatus forms an image by applying a control electric field having a polarity corresponding to recording information, to a recording medium having microcapsules including chargeable particles dispersed in a dispersion medium. The image-forming apparatus includes an alternating electric field-applying unit for applying an alternating electric field to the microcapsules. The alternating electric field is applied to the microcapsules of the recording medium before the image formed on the recording medium is rewritten. Accordingly, the chargeable particles are separated from the wall surfaces of the microcapsules and from the other chargeable particles, making it possible for the chargeable particles to perform free electrophoresis. The recording medium is initialized to improve the response performance with respect to the control electric field for forming a new image. The recording density is increased, and the blur is reduced.

  • Patent number: 4828957
    Abstract: Disclosed is a two-color heat-sensitive recording material which comprises a base sheet and a recording layer of single-layer or multi-layer structure formed on the base sheet, the recording layer comrising:(a) a diazonium salt,(b) a basic leuco dye,(c) a 2-hydroxy-3-naphthoic acid derivative which acts as a coupler compound for causing the diazonium salt to develop color when heated and which also acts as a color developing material for causing the basic leuco dye to develop color when heated, and(d) a basic substance, wherein the diazonium salt and the basic leuco dye each form a color upon application of heat, thereby giving the first image of a mixed color, and, then, after irradiation of an active ray to decompose the diazonium salt, the basic leuco dye alone forms its own color upon application of heat, thereby giving the second image whose color is different from the mixed color of the first image.

  • Patent number: 4782002
    Abstract: A photo and pressure sensitive recording medium comprising a sheet shaped supporting member, microcapsules enveloping therein at least image developing materials and photo-sensitive resins, and plastic grains having large diameter than that of the microcapsule and being softenable when exposed to external energy. The microcapsules and the plastic grains are mixedly distributed and coated on one surface of said supporting member.Since the plastic grains are not softened until they are subjected to the external energy such as heat, light and so on, the microcapsules smaller than the plastic grains can be prevented from unintentional rupturing by fingers of operators or so during the transportation or so of the recording medium even though the microcapsules are prepared to be ruptuable by small pressure such as the pressure applied by the fingers or so.
