A copying apparatus is provided with a first scanning unit for scanning a first document to expose a photosensitive material and a second scanning unit for scanning a second document to expose the photosensitive material, and, at a position where the optical path of the scanning light of the first scanning unit and the optical path of the scanning light of the second scanning apparatus align with each other, a zoom lens is disposed to modify magnification. Consequently, a lens used exclusively for a high magnification becomes unnecessary.
