Abstract
A thermal transfer recording device which records a full color image through a single recording operation with a remarkably improved recording efficiency and less power consumption. The recording device uses, as a recording medium, a heat-sensitive recording medium which colors when heated, and has a control unit to control electric energy supplied to heating elements in a line thermal head according to image data in a way to bring its level into: a white range in which the recording medium does not turn black and thermal transfer inks of an ink ribbon are not transferred; a color range in which the recording medium does not turn black and the thermal transfer inks are transferred; or a black range in which the recording medium turns black.
