Zusammenfassung:	PURPOSE:To form an image on both a photosensitive pressure sensitive microcapsule sheet and a heat developable silver salt photographic paper by providing a video signal inverting device which inverts the polarity of a video signal and inverts the negative and positive of the image on a cathode ray tube. CONSTITUTION:The video signal inverting device is provided, which inverts the polarity of the video signal so that the brightness and darkness of the image displayed on the cathode ray tube 25 may be inverted and inverts the negative and positive of the image on the cathode ray tube 25. In order to perform exposure to the photosensitive pressure sensitive microcapsule paper 2, a positive image is displayed on the cathode ray tube 25, and in order to perform the exposure to the heat developable color photographic paper 20, a video is inverted and a negative image is displayed. Thus, the color image is formed on both the microcapsule sheet 2 and the photographic paper 20 by using one machine.
