PURPOSE:To provide a high-density image with good halftone quality by employing a laminate medium which includes a plurality of porous ink layers having different pore sizes. CONSTITUTION:A base 1 carries an ink layer 2 of a laminate structure, which includes a porous resin layer 3 with a large average pore diameter, and a porous resin layer 4 with a small average pore diameter. In this structure, the amount of ink coming out varies with the thermal energy applied through a thermal head 5. Therefore, a high-definition image is obtained with faithful halftone by controlling the thermal energy to vary the amount of ink to be transferred. The large average pore diameter is 5-30mum, while the small average pore diameter is 0.5-10mum. |
