ABSTRACT:
An image recording apparatus for recording an image of an original on a photosensitive recording medium. At an exposure zone, a latent image corresponding to the original image is formed on the photosensitive recording medium through filters. The filters provide insufficient spectral transmission characteristics, yet resultant output image has sufficient quality by controlling light irradiation amount from a light source or by controlling an exposure speed in response to insertion amounts of the filters with respect to an optical path.
