Abstract

A copying machine for forming images using either ordinary color photosensitive materials or thermodeveloping photosensitive materials. The copying machine reproduces color images of high quality using a simple and small-scale device without the need for several exposure stages or complicated development processing. The copying machine comprises an image reading device which obtains a trichromatic separated signal by reading an original by photoelectric scanning, an image processing device which effects the desired image processing on the trichromatic separated signal which has been read, an exposure device which trichromatically exposes thermodevelopment and color-sensitive materials by means of the output signal from the image processing device, and a thermodevelopment and transfer device which thermally develops the exposed color-sensitive material and thermally transfers an image to image-receiving materials.
