ABSTRACT:
An apparatus for the formation of images comprising a lamp which is disposed below a photosensitive sheet staying at a buffer section and which is turned on during the period of a light-exposure step, and a light-blocking plate which directs the light from the lamp into a portion of said photosensitive sheet between a pressure-transfer section and the front end of a latent image, whereby pressure-rupturable capsules on a non-image area of the photosensitive sheet are hardened and do not rupture when pressurized at the pressure-transfer section, thereby preventing chromogenic materials contained therein from flowing out onto the pressure rollers ore other devices, preventing the pressure rollers and/or the inside of the apparatus body from being stained with the chromogenic materials, and preventing the photosensitive sheet from becoming crumpled or from causing jamming.
