ABSTRACT:
In one of the embodiments of the invention, a plurality of originals is sequentially optically scanned and the image bearing light is applied to each of a plurality of photosensitive recording sheets to form a latent image corresponding to one of the originals. The photosensitive recording sheet is brought to facial contact with a developer sheet to develop the latent image and provide a visible image on the developer sheet. The developer sheet is circulated so that it is again brought to facial contact with the subsequent photosensitive recording sheet on which another latent image is formed by optically scanning a different original. In this manner, a plurality of images on different originals are recorded in superposition on a single recording medium. In another embodiment of the invention, an image of a single sheet of original is analyzed to a character image and images of primary color components. A predetermined number of mask members are provided each having a light shielding image corresponding to each of the analyzed images. Latent images of the primary color components are formed on a single photosensitive recording sheet in superposition and the latent image of the character image is formed in another photosensitive recording sheet. The latent images of these two are developed in superposition on a single developer sheet.
