PURPOSE:To provide a direct plate making device which adopts a new image forming method and whose structure is compact. CONSTITUTION:This device is mainly constituted of a photosensitive sheet feeding mechanism (10), a cover sheet peeling mechanism (20), a color-material sheet feeding mechanism (30), a color-material sheet peeling mechanism (40), a photosensitive sheet peeling mechanism (50), a color-material sheet carrying mechanism (60), an image receiving sheet feeding mechanism, the peeling mechanisms of a color-material sheet and an image receiving sheet, an exposure mechanism (12) using a laser light beam by a digital image signal, a rotary drum (A), a pressure roller (B) and a heating and pressure roller. By image exposure, stickiness between the exposed part and the unexposed part of the photosensitive stickiness control layer of a photosensitive sheet (a) is changed. Then, pressure processing is executed by superposing the photosensitive stickiness control layer of the sheet (a) on the color-material layer of the color- material sheet. By peeling the sheet (a) thereafter, a color-material image is formed on the color-material layer side of the color-material sheet and transferred on the image receiving sheet by pressure and heating processing. |
