ABSTRACT:
According to the present apparatus, a photo-pressure sensitive paper includes thereon a chromogenic material and photo-sensitive composition etc., and microcapsules which cure in response to light. The paper is fed onto an exposure table. The unexposed microcapsules on the paper are ruptured so that the chromogenic material and photo-sensitive composition etc., which flows therefrom reacts with a developing agent provided on either the paper or a transfer sheet where the image is formed. Responsive to the detected magnification during exposure, the paper is exposed from the leading edge thereof.
