ABSTRACT:
An apparatus for the formation of images, in which a photosensitive sheet coated with pressure-rupturable capsules that are hardened by light is first transported through a light-exposure section to be illuminated by an illuminating means to obtain a latent image, and then temporarily stored in a buffer section, and transported through a pressure-transfer section consisting of a pair of pressure rollers to be pressed against an image-receiving sheet to obtain a colored image on the image-receiving sheet, and is finally wound around a take up rod, the illuminating means selectively illuminating the photosensitive sheet so as to harden some of the pressure-rupturable capsules thereon to form the latent image, and the apparatus comprising: a secondary illuminating means for entirely illuminating a predetermined portion of the photo-sensitive sheet so as to harden all the pressure-rupturable capsules thereon when said portion of the photosensitive sheet is being transported alone through the pressure-transfer section without the image-receiving sheet after the jamming of the image-receiving sheet occurs and the jammed sheet is removed from the body of the apparatus.
