せる。That is, by bringing the heating means into contact with the surface of the photosensitive material support in the lapse rate drying region, heat is rapidly applied to the photosensitive material, and even if the heating means has a low calorific value, water in the photosensitive material can be efficiently evaporated. . Also, the surface temperature of the heating means is 6
When the temperature is 0 to 95° C., moisture can be evaporated without causing deformation or damage to the photosensitive material, and the photosensitive material can be efficiently dried. The surface temperature of the heating means is 60"C
If it is less than that, the photosensitive material will not be heated well and cannot be dried efficiently. Furthermore, if the surface temperature of the heating means exceeds 95°C, the photosensitive material may be deformed or damaged.

短時間で乾燥することができる。If a liquid removal section is provided in the drying section, the drying area of the water loss rate of the photosensitive material is after the liquid removal section on the photosensitive material transport path in the drying section. Further, if there is no liquid removal section in the drying section, the lapse rate drying area may be near the photosensitive material loading section in the drying section. The lapse rate drying region in the drying section can be determined experimentally, and by contact heating the surface of the photosensitive material support in the lapse rate drying region, the photosensitive material can be efficiently dried in a short time with low power.
