    • The invention provides a thermal transfer recording method which can improve surface flatness of a protective layer in the thermal transfer recording method in which the protective layer is transferred by a thermal head, and a thermal transfer recording apparatus which can realize the thermal transfer recording method. In the thermal transfer recording method in which a protective layer provided in a substrate sheet of a transfer sheet is transferred onto an image of a printing material by heat of a heat generation portion of a thermal head, arithmetic mean roughness Ra defined in JIS B 0601 is set to a value not more than 30 nm at an interface on the side of the substrate sheet of the protective layer, the part is separated into a plurality of separate portions by providing a plurality of slits in the heat generation portion, a plurality of individual electrode portions are arranged on the upstream side in a feed direction y of the plurality of separate portions, a common electrode portion is arranged on a downstream side in the feed direction y of the heat generation portion, and a flat pressurizing surface S is formed on the downstream side of the plurality of separate portions in the heat generation portion and the common electrode portion.
    • 本发明提供了一种热转印记录方法,其可以改善保护层通过热敏头转印的热转印记录方法中的保护层的表面平坦度,以及能够实现热转印记录方法的热转印记录装置。 在通过热敏头的发热部分的热量将设置在转印片的基片上的保护层转印到印刷材料的图像上的热转印记录方法中,JIS B 0601中定义的算术平均粗糙度Ra 在保护层的基板一侧的界面处设定为不大于30nm的值,通过在发热部中设置多个狭缝将部分分离成多个分离部,多个 在多个分离部的供给方向y的上游侧配置有单独的电极部,在发热部的供给方向y的下游侧配置有公共电极部,形成平坦的加压面S 在发热部和公共电极部的多个分离部的下游侧。
