摘要： PURPOSE:To reduce running cost, by providing a recording body consisting of a porous membrane layer impregnated with heat-meltable ink, a porous layer base provided thereon, and a means for applying heat to the surface of the recording body according to a pattern. CONSTITUTION:A signal from the outside is sent to a heat generating part 4 to selectively allow heat generators 5 arranged in an arrays form to generate heat, and the heat is conducted to a porous membrane layer 1b and a porous base 1a of the recording body 1 contacted with a heat generating part 4 to lower the viscosity of the ink 2 infiltrated in said membrane layer 1b. The ink 2 having a lowered viscosity permeates the porous membrane layer 1b to form an ink image having a predetermined shape according to the heating part of the heat generating part 4. Next, the recording body 1 rotates and moves in the direction shown by an arrow and, before the ink is solidified in the downward direction, the ink image formed on the porous membrane layer 1b is contacted with the recording body 1 and transferred to a recording medium 3 pressed by a platen roller 6 at a position opposed to said recording body 1 to form an image on the recording medium 3.

摘要： PURPOSE:To record a sharp image, by a method wherein a predetermined heat generator is allowed to generate heat according to image information on the basis of an external signal and the viscosity of the ink in an ink sump provided in the vicinity of said heat generator is lowered and the ink is transferred to a recording medium while the ink is replenished to the ink sump from an ink supply system. CONSTITUTION:When a voltage is applied between each signal electrode 7 and each scanning electrode 5 according to image information on the basis of a signal from the outside through each signal brush 13 and a scanning brush 11, the largest current flows to the intersecting part of both electrodes 5, 7. The heat generator 6 at said intersecting part generates heat, and the viscosity of ink 18 of an ink sump 8 provided on the heat generator 6 is lowered and the ink is transferred to a recording medium 2 to form an image on the recording medium 2. Since no sufficient current flows to the heat generator 6 of the ink sump 8 of a non-recording part receiving no signal from the outside, the ink 18 of said ink sump 8 holds high viscosity as it is and, no ink is transferred to the recording medium 2.

摘要： PURPOSE:To prevent generation of trailing or fog in an image, by forming a recording head so that a heat generating body may generate heat corresponding to an image signal and the ink in a housing is supplied to an ink sump through an ink passing hole and reduced in its viscosity to be transferred to a medium to be recorded. CONSTITUTION:An insulating substrate 4 and a heat generating body 5 comprising ruthenium oxide (RuO2) are provided to a part of a housing 2. At first, when a voltage pulse is applied to the heat generating body 5 through an electrode 7, the semisolid ink 3 in vicinity of the heat generating body 5 is heated. Said ink has a high viscosity at ambient temp. but when heated, it passes through ink passing holes 6 because its viscosity is reduced, and it spreads in the ink sump 9 and radiates heat at this time to again return to the semisolid state. Next, when voltage is applied to the heat generating body 5 corresponding to an image signal, said heat generating body 5 selectively generates heat and the semisolid ink 3 is lowered in its viscosity by said heat to be released from the ink sump 9 and transferred to recording paper 10. Therefore, trailing or fog is hard to generate in the transferred image and a sharp image can be recorded.

摘要： PURPOSE:To prevent the generation of trailing or fog in an image, by providing a window forming an ink sump divided into plural sections on a heat generator and forming an ink passing part to a part of said window. CONSTITUTION:A window 7 is formed in a frame shape so as to form an ink sump 8 divided into plural sections in an array state on a heat generating body 4. Ink has a high viscosity at ambient temp. but is lowered in its viscosity upon being heated to pass through ink passing holes 5 to spread in the ink sump 8 and radiates heat at this time to again return to a semisolid state. Next, when voltage is applied to the heat generating body 4 corresponding to an image signal, the heat generating body 4 selectively generates heat and the semisolid ink 3 is reduced in its viscosity and released from the ink sump 8 to be transferred onto recording paper 9. Since ink passing parts are formed to the window 7 by notches in the downstream direction of the movement of the transferred ink, the ink is not dragged to prevent a trailing of the ink.

摘要： PURPOSE:To prevent the trailing of images of fogging from occurring and record clear images, by transferring an ink contained in an ink reservoir onto a recording medium through lowering the viscosity of the ink, and replenishing the ink contained in a housing into the ink reservoir through an ink-passing hole. CONSTITUTION:With a voltage pulse applied to a heat generating element 4 through electrodes 6, the element 4 generates heat, thereby heating a semi-solid ink 3 in the vicinity of the element 4. The ink has a high viscosity and can not flow through an ink-passing hole 5 at normal temperature, but when it is heated, the viscosity thereof is lowered to permit it to flow through the hole 5. The ink 3 having flowed through the hole 5 spreads into an ink reservoir 8, and due to the attendant release of heat, the ink is returned into the semi- solid state or a nearly semi-solid state. Next, with a voltage applied to the heat-generating elements 4 according to an image signal, the elements 4 selectively generate heat, whereby the semi-solid ink 3 in the ink reservoir 8 is lowered in viscosity, is released from the ink reservoir 8, and is transferred onto a recording paper 9 fed in the direction of an arrow (b).

摘要： PURPOSE:To obtain an image excellent in contrast with a small quantity of heat, by constructing the device of a movable image-forming sheet which is varied from a transparent state to a non-transparent state by heating, a heating means for conducting recording on the sheet, and a dark-color fixed plane provided at a position opposite to the image-forming sheet in a display element. CONSTITUTION:An image-forming sheet 4 has a high-molecular recording material layer superposed on a substrate of polyethylene terephthalate or the like. This high- molecular recording material is formed of a thin layer of stable blended polymers of two kinds or more, and it is stretched in the shape of an endless belt between a driving roller 2 and a follower roller 3 and driven thereby intermittently. An image thereon is transparent (transmittance is 90% or above) at normal temperatures and it turns to be non-transparent (transmittance is 10% or below) by heating and subsequent rapid cooling. In order to vary the non-transparency of the image-forming sheet efficiently by a heating means, heat-absorbing black substances 5 and 5a fixed in a opposition to the heating means are provided in contact with the image-forming sheet 4. The heat-absorbing black substance 5 is formed by coating a metal plate with a material which is prepared by dispersing a black pigment such as carbon black, for instance, in polyethylene terephthalate or the like.

摘要： PURPOSE:To provide a recording material which enables information to be written and erased in correspondence with exposure to an optical information, by laminating a photoconductive layer and a thermal layer on each other and clamping the laminate by conductive layers, or by clamping a photoconductive layer by conductive layers and laminating a thermal layer on one of the conductive layers. CONSTITUTION:A transparent conductive layer 12 and a photoconductive layer 13 are provided on a transparent resin film 11. On the layer 13 is laminated a thermal layer 14 which is transparent at room temperature but is turned white and opaque when being heated. A conductive layer 15 is further provided on the thermal layer 14 by vapor deposition, like the conductive layer 12. When the photoconductive layer 13 is exposed to optical information under the condition where voltages of opposite polarities are impressed respectively on the conductive layers 12 and 15, an electric current flows between the electrodes through the photoconductive layer 13 made conductive and the thermal layer 4, generating Joule heat at the part through which it flows. The Joule heat makes the thermal layer 14 opaque, whereby recording is completed.
