By the way, in the conventional image recording apparatus as described above, the photosensitive material to be image-exposed in the exposing section is simply exposed at the ambient temperature. However, due to the characteristics of the photosensitive material, the color density and the color balance are liable to fluctuate due to the change in the exposure temperature. Therefore, if the ambient temperature at the time of exposure changes, this has been an obstacle to obtaining a stable high-quality image. In particular, in order to reduce the size of the image recording apparatus as a whole, it is necessary to dispose a heat development transfer section near the exposure section, and the temperature change of the heat development transfer section directly affects the exposure section, so that the above-mentioned drawbacks are caused. It is necessary to take countermeasures to solve the problem.

For example, as shown in FIG. 2, reflected light S from a document is irradiated to an exposure point X using a plurality of mirrors (not shown) or the like, and the photosensitive material
In the case of an image recording apparatus configured to carry out scanning exposure while passing through the exposure point X while transporting the photosensitive material 8, the photosensitive material 18 to be transported is maintained at a predetermined temperature by providing a light-transmitting heat block 56 at the exposure point X. The temperature can be raised and maintained for exposure. Even in this case, since the photosensitive material 18 to which the image of the document is exposed passes through the exposure section (exposure point X), the temperature is raised to a constant temperature by the heat block 56 and is maintained. The photosensitive material 18 is exposed at a constant temperature even if the
Fluctuations in color density and color balance are reduced, and a stable high-quality image is obtained.

In the above embodiment, the light from the light source 34 is applied to the original and the reflected light is applied to the exposure transfer stage 1.
Although the image recording apparatus 10 has a configuration in which the photosensitive material 18 held in 4 is sequentially scanned and exposed in a slit shape, the present invention is not limited to this, and the image recording apparatus 10 is configured to scan and expose a photosensitive material to a light beam by an image signal. It may be a recording device.
Even in this case, the photosensitive material is exposed at a constant temperature irrespective of changes in the ambient temperature, and fluctuations in color density and color balance are reduced, so that a stable high-quality image can be obtained.

As described above, in the image recording apparatus according to the present invention, even if the photosensitive material is liable to change in the photosensitive characteristic due to the temperature change, the change in the color density and the color balance is reduced to obtain a stable high image quality. It has an excellent effect that an image can be obtained.
