Thermal development apparatus

1. A thermal development apparatus comprising:

a thermal development section for heating a photosensitive thermal developable recording material to visualize a latent image recorded on an image-forming layer on both faces of the photosensitive thermal developable recording material by a heating unit,

a cassette holder section for holding a cassette that houses the photosensitive thermal developable recording material therein,

a conveyor unit for taking the photosensitive thermal developable recording material out of the cassette held in the cassette holder section and conveying the photosensitive thermal developable recording material to the thermal development section, and

a control unit for controlling at least one of a heating temperature and a conveyance speed in the heating unit of the thermal development section,

a moisture sensor to determine the moisture content of the photosensitive thermal developable recording material by detecting a moisture content inside or around the thermal development apparatus,

wherein the control unit is provided with a moisture correction information of the photosensitive thermal developable recording material and the control unit suitably corrects and controls the at least one of a heating temperature and a conveyance speed in the heating unit from a moisture content of the photosensitive thermal developable recording material on the basis of the moisture correction information thereof during thermal development of the photosensitive thermal developable recording material.

2. The thermal development apparatus according to claim 1 , which comprises a moisture information receiver unit for receiving a moisture information memorized by memory unit for memorizing a monitor information from the moisture sensor.

3. A cassette to be held in a thermal development apparatus, which houses a photosensitive thermal developable recording material therein and comprises a moisture sensor,

wherein the moisture sensor is for detecting a moisture content inside or around the cassette, and

which further comprises a memory unit for memorizing a monitor information from the moisture sensor.

4. The cassette according to claim 3 , wherein the moisture sensor and the memory unit are on a side face of the cassette.

5. A thermal development process for thermally developing a photosensitive thermal developable recording material, comprising:

detecting a moisture content of the photosensitive thermal developable recording material by a moisture sensor disposed inside or around a thermal development apparatus;

transmitting the detected moisture content from the moisture sensor to a control unit; and

controlling at least one of a heating temperature and a conveyance speed in a heating unit of a thermal development section from the detected moisture content on the basis of a moisture correction information.
