Abstract
In an exposure device in an image recording apparatus, a photosensitive recording medium is exposed with light containing an image of an original to thereby form a latent image corresponding to the original. In view of the fact that photosensitivity of the recording medium changes depending upon some factors, such as a temperature of the recording medium per se, an intensity of light irradiated onto the recording medium, the temperature of the recording medium is controlled so that an optimum photosensitivity is obtained. The change of the light intensity is compensated for by changing the temperature of the recording medium. To this effect, the temperature of the recording medium and the light intensity of a light source are sensed and the recording medium is heated by a heater element so as to indicate an optimum photosensitivity.
