PURPOSE: To eliminate the refill of ink and toner, to facilitate printing control and to perform proper printing by utilizing a laser instead of the ink and the toner. CONSTITUTION: A continuous form 21 having a heat sensitive agent layer 24 on a printing surface is fed in a predetermined direction, the layer 24 of the form 21 fed to a predetermined position is irradiated with a laser from a laser oscillator 4 based on previously inputted printing data, and color is developed in the area, irradiated with the laser beam, of the layer 24, thereby forming a desired print pattern in the colored area. |
