Abstract
An image processing apparatus is equipped with an original document illuminating lamp, a reflector arranged in association with the lamp and having a color-compensating anodic oxidation coating formed on at least a part of a reflecting surface of the reflector, and a photosensitive member adapted to receive light from an original document upon exposure of the original document to light from the lamp and having an oversensitive range in the spectral sensitivity characteristics thereof. The reflector is made of aluminum or an aluminum alloy. Owing to the provision of the color-compensating anodic oxidation coating, the reflectivity of the reflector to light in a wavelength region corresponding to the oversensitive range of the photosensitive member is smaller than its reflectivity to light in wavelength region other than the first-mentioned wavelength region.
