Thermal development apparatus and thermal development process
View Patent ↗A thermal development apparatus for thermally developing a thermal developable recording material in a thermal development section, the thermal developable recording material having a latent image formed in advance, wherein the thermal development section has: a heating member made of a porous body having a gas permeability, the heating member having a heating surface that is disposed so as to face a surface of the thermal developable recording material; and an air feed unit for feeding heated air to the thermal developable recording material through the heating member.
1. A thermal development apparatus for thermally developing a thermal developable recording material in a thermal development section, the thermal developable recording material having a latent image formed in advance,
wherein the thermal development section comprises:
a heating member made of a porous body having a gas permeability, the heating member having a heating surface that is disposed so as to face a surface of the thermal developable recording material;
an air feed unit for feeding heated air to the thermal developable recording material through the heating member; and
which further comprises a pressure reducing machine for sucking air within the pressure chamber and bringing the thermal developable recording material into contact with the heating surface.
2. A thermal development apparatus for thermally developing a thermal developable recording material in a thermal development section, the thermal developable recording material having a latent image formed in advance,
wherein the thermal development section comprises:
a heating member made of a porous body having a gas permeability, the heating member having a heating surface that is disposed so as to face a surface of the thermal developable recording material;
an air feed unit for feeding heated air to the thermal developable recording material through the heating member; and
wherein the heating surface is provided in one of an oblique and a vertical position against a horizontal direction, and the thermal development apparatus has a stopper for stopping the thermal developable recording material at a position opposite to the heating surface.
3. A thermal development process which performs a thermal development in a state that a traveling of a thermal developable recording material is stopped, the thermal developable recording material having a latent image formed in advance,
wherein the thermal development process comprises performing the thermal development by sucking air through a porous member so that the porous member and the thermal developable recording material bring into contact with each other.
4. The thermal development process according to claim 3 , which comprises performing the thermal development sequentially every region of the thermal developable recording material that is divided into at least two regions along a traveling direction of the thermal developable recording material.
