A copying apparatus or the like having means for scanning the original to form a line image continuously on a photosensitive member, thereby forming an entire image of the original. A photosensor is provided to scanningly detect the density of the original at each phantom segment of the original. Each segment of the original is reproduced under an image forming condition determined on the basis of the density of the segment of the original detected by the photosensor so that the original is reproduced under the image forming condition which is proper for each of the segments. The image forming condition for one of the end segments with respect to the direction of the scanning operation, however, is not determined on the basis of the existing or detected density, but is predetermined or determined independently of the existing or detected density of that segment, so as to provide a clear image at the area corresponding to the end. The similar control may be applied to the other end segment, too.
