Abstract
An apparatus for transporting a photosensitive sheet in which the photosensitive sheet is drawn out by a predetermined length, with the foremost portion of its image-forming area being illuminated by a lamp, and is transported backward by the same length before an image-forming process, and accordingly pressure-rupturable capsules on the said foremost portion of the image-forming area of the photosensitive sheet are hardened, thereby no colored image being formed on the corresponding portion of an image-receiving sheet in the image-forming process, so that the foremost portion of the image-receiving sheet does not stick to an upper heat roller and can thus be readily separated from heat rollers.
