PURPOSE: To copy originals of both characters and a photograph sharply and accurately by providing an exposure scanning means for originals and a means which varies the moving speed of a photosensitive body in one body.

CONSTITUTION: When a speed changeover switch 27 is shifted to a side H, both motors 23 and 26 rotate at high speeds and a photosensitive drum 3, the 1st movable mirror 7 etc., move high speeds to widen a gradation area on the surface of the photosensitive drum 3. When the speed changeover switch 27 is shifted to a side L, both motors 23 and 26 rotate at low speeds and the photosensitive drum 3, the 1st movable mirror 7, etc., move at low speeds to narrow down the gradation area on the photosensitive drum 3. Therefore, when a character original is copied, the changeover switch is shifted to the side L and when a photgraphic original is copied, the switch is shifted to the side H. Thus, both character and photographic originals are copied sharply and accurately.
