Abstract
In an image recording apparatus for recording an image of an original document on a photosensitive recording sheet, a light source such as a halogen lamp is provided which emits a light and applying it to the image face of the original document while moving the latter. The photosensitive recording sheet is exposed to the resultant image bearing light, in which the photosensitive recording sheet is moved at a speed equal to the moving speed of the original document. A light intensity sensor detects the intensity of the light applied to the original document, and when the intensity of the light applied thereto is lowered than a required level, the moving speeds of both the photosensitive recording sheet and the original document are lowered to thereby maintain an exposure rate at substantially constant.
