PURPOSE:To form recording pictures of high accuracy void of tailing at accelerated recording speed, by stacking a high-frequency heat-sensitive sheet made up by dispersing hydrated aluminosilicate to a binding agent on a heat-sensitive recording material, and by applying a high-frequency electromagnetic field. CONSTITUTION:A high-frequency heat-sensitive sheet is built up in such a manner that 5-300 weight portions -preferably, 10-150 weight portions- hydrated aluminosilicate -preferably, granular, acicular or flat and 0.01-10mu grain size- are added to a 100 weight portion binding agent of polyethylene, polyester, etc., dispersed and changed into sheet-like shapes. The heat-sensitive sheet 1 and a heat- sensitive recording material 2 are stacked, a recording electrode 3 is arranged at the sheet 1 side, currents corresponding to pictures are sent to the electrode 3 from a recording power source 5, a high-frequency electromagnetic field is applied between the recording electrode 3 and an opposite electrode 4, the recording material 2 is color-formed and the pictures are recorded. Sodalites, such as, stone, etc. and synthetic zeolite are desirably employed as the hydrated aluminosilicate. |
