Zusammenfassung:	PURPOSE:To form a good color image which is excellent in the balance of color by making the optical path of separated light corresponding to the photosensitive wavelength area of a photosensitive agent whose sensitivity is low out of the photosensitive agents of a photosensitive sheet shorter than any other optical path of separated light. CONSTITUTION:In the case of exposing the photosensitive sheet, the reflection films of color separation prisms 21R and 21G reflect or transmit white light every color to separate the optical path. The respective color modulators 27R, 27G and 27B modulate the light intensity based on modulating signals corresponding to the respective red, green and blue components. The light made incident from the modulator 27R and a color separation prism 24G is synthesized to be the single optical path to be the white color again by a color synthesis prism 24R. As for the optical path of the separated light, the optical path of the separated light corresponding to the photosensitive wavelength area of the photosensitive agent whose sensitivity is low out of the respective photosensitive agents is made shorter than any other optical path of the separated light. Thus, the image which is well-balanced in color is formed.
