摘要:
A sublimation type thermosensitive image transfer recording medium which can be used in repetition, comprising a support; a dye supplying layer formed on the support, comprising a sublimable dye and at least one binder agent in which the sublimable dye is dissolved or dispersed; and an image transfer facilitating layer formed on the dye supplying layer, comprising the sublimable dye and at least one organic binder agent in which the sublimable dye is dissolved or dispersed, the dye supplying layer and the image transfer facilitating layer being structured in such a manner that when the dye supplying layer and the image transfer facilitating layer are separately formed on a substrate, and the layers are separately superimposed on the same receiving sheet, with application of an equal quantity of thermal energy thereto, the amount (weight/unit time.unit area) of the sublimable dye transferred from the dye supplying layer to the receiving sheet is greater than the amount (weight/unit time.unit area) of the sublimable dye transferred from the image transfer facilitating layer to the receiving sheet.
摘要:
A thermosensitive recording method comprising the steps of superimposing a sublimation-type thermosensitive image transfer recording medium on an image receiving sheet, and applying heat imagewise to the recording medium while moving the recording medium and the image receiving sheet in such a manner that the running speed of the image receiving sheet is greater than that of the recording medium. The recording medium for use with the above method comprises an ink layer containing a sublimable dye and one or more organic binder agents in which the sublimable dye is dispersed in the form of granules.

摘要:
An information recording medium is composed of a support; a thermosensitive recording layer provided at least on one side of the support, the thermosensitive recording layer being composed of a matrix resin and an organic low-molecular-weight material which is dispersed in the matrix resin, the transparency of the thermosensitive recording layer being reversibly changeable depending upon the temperature thereof; and a thermal transfer image receiving layer for thermal printing thereon by thermal transfer recording, which is provided at least on one side of the support, opposite to the thermosensitive recording layer. A printing method using the above information recording medium is also provided.The thermosensitive recording layer and the thermal transfer image receiving layer may be replaced by a single sublimable material receiving reversible thermosensitive recording layer which have the two functions of the thermosensitive recording layer and the thermal transfer image receiving layer.
摘要:
Thermal recording structure and a method of thermal recording wherein a desired sublimation dye image is formed on an information recording medium provided with a thermal recording layer having a sublimation dye accepting function on at least one surface of a base substrate. The transparency of the thermal recording layer is reversible depending upon temperature to which the medium is heated. At least the sublimation dye image portion of the medium is heated to a temperature sufficient to reverse the transparency of the transfer image.

摘要:
A fixing device includes: a rotatable endless fixing belt; a nip forming member arranged inside the fixing belt; a facing rotating body that abuts the nip forming member via the fixing belt to form a nip portion with the fixing belt; a heat source that directly heats up the fixing belt at a portion other than the nip portion; and a supporting member that supports the nip forming member. The fixing device conveys a recording medium carrying an unfixed image to the nip portion to fix the unfixed image to the recording medium, and the supporting member includes a rising portion extending in an abutting direction of the facing rotating body against the fixing belt and having a tip close to an inner circumferential surface of the fixing belt, and is set to have a section modulus of 200 mm3 or higher.
