Abstract

An image-forming apparatus includes a platen on which an original is placed so that a first surface of the original is positioned at an exposure area, a first sensor for detecting that a second surface of the original which is the opposite surface to the first surface has an image, and a second sensor for detecting the transmittance of the original. The image-forming apparatus also has an exposure lamp which is arranged near the platen to expose the first surface positioned at the exposure area, a voltage source coupled to the exposure lamp, a control unit for adjusting the voltage applied from the voltage source to exposure lamp corresponding to the transmittance in the case that the first sensor detects that the second surface has an image, and an image-forming unit for forming a copying image on the basis of the light image.
