PURPOSE: To realize a small size and light weight for the titled copying machine, by exposuring an original and fixing a toner image with a single light source.

CONSTITUTION: The light emitted from a strobo light source 1 is reflected directly and via a reflecting shade 2 and irradiates the copying paper 4 which is carried by a carrying device 3 of a fixing part. Thus a toner image 5 copied on the paper 4 is printed. At the same time, a part of the light emitted from the light source 1 passes through a slit 2a provided to the shade 2 and then reflected by the mirror 6 and 7 to irradiate the surface of an original 9 put on a transparent original board 8. This reflected light is condensed by a lens 10 and made incident to the charged surface of a photoreceptor belt 11 to form an electrostatic latent image. With plural times of light emission of the light source 1, the fixing of one time is performed for the copying and the exposure of original of one time is performed with the light emission of one time.
