ABSTRACT:
Image formation device includes an optical image memory which is shaped like a flat board and includes an image area formed almost in the center portion for storing an image and a void area surrounding the image area, where no image is written, the image stored being optically recognizable and able to be repetitively read; image writing means for writing the image in the optical image memory by the selectively irradiating the image area in accordance with data on a desired image; exposing means for exposing a photosensitive material by irradiating light through the optical image memory to the photosensitive material from which color coupler in a non-exposed portion is discharged by applying pressure; light control means for controlling a width of light irradiated to an area of the photosensitive material through the void area in the direction of the widthwise extension of the photosensitive material so that the width of light is identical with the width of the photosensitive material; and developing means for pressing and developing the exposed photosensitive material overlaid with an image receiving medium where the image is to be formed.
