ABSTRACT:
A color copier including an exposure light source exposes an original document with red, blue, and green light, on a photosensitive film having a substrate and an ink coating which includes ink particles of multiple colors carried on the substrate, and on which a reproduction of the original document is formed, in response to the light exposure, through a reaction of ink particles of the color which corresponds to the wavelength of the light reflected from the original document. The color copier further includes a lightproof film case for storing the photosensitive film; an image forming lens for forming an image of the original document on the photosensitive film by focusing the reflected light; a copy paper feeder for feeding a copy paper; a fixer for fixing the image formed on the photosensitive film on the copy paper; a separation claw which separates the photosensitive film from the copy paper after the fixing of the image; and a film take-up shaft for winding thereon the photosensitive film. The film take-up shaft is located downstream from the separation claw in the direction of paper transport, and is formed with an insertion slot for inserting a leading edge of the photosensitive film.
