Thermal recording apparatus

摘要

The thermal recording apparatus includes an image recording device and a light irradiation device. The image recording device records an image by heating imagewise a thermal recording material. This material includes a color forming agent and a developer and optionally a light absorption dye on a substrate and is colored at a density corresponding to an added thermal energy. The light irradiation device irradiates light containing an absorption wavelength of 400 nm to 700 nm of a color forming dye of the thermal recording material to the thermal recording material heated and colored by the image recording device. The apparatus can form an image with a high contrast at a high sensibility while a sufficient dynamic range is secured, and the stability of the formed image is also high.
