First, the heating element of the thermal head 2 is energized in response to an image signal corresponding to magenta when a multicolor image is color-separated. The power applied to the heating element at this time is 0.2
w/dot. A transparent image is formed on the sheet 1 in accordance with this energization. The sheet 1 that has been energized for a predetermined amount is conveyed to a position facing the light source 3, and at the same time, a green filter 1O for magenta recording is set facing the light source 3. Then, exposure from the light source 3 is performed.

At the same time, red filter 9 or light source 3 for cyan recording
is set opposite to. Then, exposure from the light source 3 is performed. Similar transparent image formation and exposure are performed for yellow, and a transferred image is formed on the photosensitive recording medium 4 by three exposures. Thereafter, the photosensitive recording medium 4 is conveyed by a pressure roll 6, and is conveyed to the pressure roll 6 together with the image receiving paper 5. Only the uncured microcapsules are destroyed by the pressure roll 6 and transferred to the image receiving paper 5. Receiving paper 5
The image receiving paper 5 on which a clear multicolor image has been recorded by the color developer applied thereto is discharged to a paper discharge tray 13. Further, the sheet 1 is conveyed after three exposure passes r, and is heated to about 150° C. by a heating roll 7. It then returns to its opaque state upon cooling.
