PURPOSE:To form a high resolution and sharp image by providing material having an absorption wavelength band almost identical to that of photosensitive material or including said band inside a base or its both or one surface. CONSTITUTION:Light made incident on a point B on a photosensitive member 1 is irregularly reflected by a microcapsule 11 or a binder 12. When the photosensitive wavelength band which are reflected light reaches includes the wavelength band of projected light, the microcapsule 11 is cured. Since light repeatedly scattering in the layer between the microcapsule 11 and the binder 12 rapidly decreases its quantity whenever it scatters, it hardly spreads around the point B. Out of the lights made incident on the base 10, one in the photosensitive wavelengths band of the microcapsule 11 overlaps with that of a carbon black in the base 10, and consequently much of the light is absorbed in the base 10. As a result, there is less halation due to stray light. Thus, a sharp image with a high resolution and less halation can be obtained. |
