Next, the automatic development processing apparatus of the present invention will be described. The drying section of the automatic development processing apparatus of the present invention is a photosensitive material drying apparatus that dries the photosensitive material conveyed along the conveying path, and exposes the photosensitive material to a plurality of heat rollers whose outer periphery is heated by a heat source. The back surface is alternately wound, and the photosensitive material is heated by the amount of heat given based on the temperature of the outer periphery of the heat roller and the contact time with the heat roller,
It is characterized in that moisture is evaporated from the surface of the photosensitive material which is not in contact with the heat roller. Further, a drying air can be blown to the surface side of the photosensitive material which is not in contact with the heat roller to accelerate the evaporation of water. The temperature of the outer circumference of the heat roller is 80 ° C. or lower, and the contact time between the heat roller and the photosensitive material is 1.5 to 5 seconds.

The drying device of the present invention is a photosensitive material drying device for drying a photosensitive material conveyed along a conveying path,
A first heat roller that has a heat source inside and is wound so that one side of the photosensitive material is in contact with a part of the peripheral surface, and the other side of the photosensitive material is in contact with a part of the peripheral surface that has a heat source inside Of the photosensitive material, and the second heat roller that is wound around the first heat roller and the second heat roller that are conveyed while being wound around the first heat roller and the second heat roller. The chamber has a chamber formed along the width direction and having a slit that communicates the inside with the vicinity of the transport path, and a dry air supply unit that supplies dry air into the chamber. By setting the temperature of the heat roller of the drying device of the present invention and / or the temperature of the drying air blown to the surface that is not in contact with the heat roller, based on the conditions of the atmospheric temperature and the humidity of the installation location of the automatic development processing device, The temperature of the heat roller and / or the drying air temperature of the surface not in contact with the heat roller can be dried at the minimum necessary temperature.

According to the drying apparatus of the present invention, the amount of heat applied to the photosensitive material by the heat roller can be obtained based on the temperature of the outer circumference of the heat roller and the contact time between the heat roller and the photosensitive material. That is, the drying capacity is determined by the product of the surface temperature of the heat roller and the contact time, so by increasing the amount of winding around the heat roller,
Good drying can be performed even when the contact time is extended and the temperature of the outer periphery of the heat roller is lowered without slowing the conveying speed. Therefore, even if the paper or film is accidentally jammed and the photosensitive material is stagnant in the vicinity of the heat roller, the outer peripheral temperature of the heat roller is low and overdrying can be prevented. And prevent damage such as deformation. Further, when one surface is heated by the heat roller, water is evaporated from the other surface. At this time, by blowing a drying air to the other surface, this evaporation can be promoted and the material is dried in a short time. be able to. The drying apparatus of the present invention has a short contact time between the photosensitive material and the heat roller of 1.5 seconds to 5 seconds, and therefore can dry the entire drying time in 6 seconds to 20 seconds. Since the surface is kept at 80 ° C. or lower, the image can be dried with good dimensional stability without impairing the image quality.

According to the drying apparatus of the present invention, the emulsion surface of the photosensitive material is heated by the first heat roller. As a result, the evaporation on the back surface starts, and the evaporation is accelerated by the dry air supplied to the chamber by the dry air supply means. Also,
When the back surface of the photosensitive material is heated by the second heat roller, evaporation on the emulsion surface starts, and the evaporation is accelerated by the dry air. Here, since the photosensitive material is wound around the first heat roller and the second heat roller, it is heated for a time corresponding to the winding amount. Therefore, even if the temperatures of the first heat roller and the second heat roller are lowered, the amount is compensated by extending the time (extending the time during which the photosensitive material is in contact with the first and second heat rollers). Therefore, proper heat treatment can be performed. Therefore, even if the photosensitive material is clogged and the photosensitive material stops in contact with the first or second heat roller, wrinkles and the like due to local heating do not occur, and the quality can be maintained. . In addition, the temperature of the conventional linear transport nip type heat roller (100 ° C
The temperature becomes extremely low with respect to (to 150 ° C.), and the maintenance workability can be improved without impairing the safety of the operator during maintenance.
