PURPOSE: To make it possible to achieve high speed precise recording, by a method wherein a plurality of thermal heads each having such a configuration that rod-shaped thermal elements are gathered in parallel are arranged with respect to recording paper at predetermined intervals and each thereof is put in supporting recording at a predetermined position.

CONSTITUTION: Each thermal head 10 is formed by gathering rod shaped thermal elements 11 is parallel and heaters 12 are provided to one end part thereof while lead wires 13 are extended to the other end part thereof. Two of these thermal heads 10A, 10B are provided, for example, at an interval of 10mm and put in charge of recording positions with respect to heat sensitive recording paper 21 conveyed through pinch rollers 22A, 22B while the recording informations, which are obtained by subjecting the image data from the other apparatus to treatment such as modulation in a control part to store the same, from line memory 23 are imparted at every a predetermined amount to perform recording in charge. By this method, the speed acceleration of recording is achieved, a precise recording image is obtained, a line image can be made thick and multi-color recording can be performed.
