<p>PURPOSE:To enable thermal writing an reusing thereof by obtaining a visible image by a thermal impressing means to a thermochromic layer which becomes transparent and opaque reversibly. CONSTITUTION:A thermochromic layer 1 comprises particles of an org. low molecular material dispersed in a resin, wherein a transparent conductor layer 3 is formed on a surface opposite to the thermochromic layer 1 of a transparent base body, and a photoconductive layer 4 is formed on the transparent conductor layer. By this constitution, an image formed thermally on the thermochromic layer 1, if it is once formed, can be formed several times on the photoconductive layer by uniform general exposure basing on the image formed on the thermochromic layer as a block. By developing the formed image, many sheets of same originals are outputted rapidly. Moreover, since the thermochromic layer 1 is reversible, the photosensitive body is reusable optionally.</p> |
