Abstract: 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.

Abstract: A thermal image recording apparatus has: a thermal head having a glaze in which thermal recording dots are arranged in a one direction, the thermal head conducting thermal recording on a thermal recording material that is to be in contact with the glaze, and transporting the thermal recording material in a direction perpendicular to the arrangement direction of the thermal recording dots; heating unit, disposed downstream from the thermal head in the transport direction, for reheating the rear face opposite to the recording surface of the thermal recording material; and correcting and cooling unit for cooling the reheated thermal recording material while causing the rear face to be concaved.

Abstract: A thermal developing apparatus for thermally developing a latent image formed on a thermal developing recording material by a thermal developing portion, the apparatus comprising: a heating unit that heats the thermal developing recording material carried to the thermal developing portion, the heating unit comprising a plurality of heating portions that are aligned in a direction that intersects orthogonally with a carrying direction of the thermal developing recording material; and a plurality of temperature measuring portions that measure temperatures of the plurality of heating portions respectively, each of said plurality of temperature measuring portions being arranged to measure a center portion of a temperature distribution in each of said plurality of heating portions.
