Abstract: A light and heat sensitive recording material passes through an accommodating section and a heat-development section and reaches an optical recording section. At the optical recording section, optical recording is effected, at the heat-development section, development is effected and at the photo-fixing section, fixing is effected upon the light and heat sensitive recording material. Finally, the light and heat sensitive recording material is discharged from a discharge section to the outside. At the photo-fixing section, white light from the optical recording section is used and irradiated onto the light and heat sensitive recording material. Thus, by using the same light source, a latent image can be appropriately recorded on the light and heat sensitive recording material and the heat-developed image can be reliably fixed.

Abstract: An image-recording apparatus including a casing section that encases a light and heat sensitive recording material therein; an optical recording section that exposes to light a light and heat sensitive recording material fed from the casing section, and thereby records a latent image thereon; a thermal developing section that develops the latent image with heat; a moisture content-controlling section that controls moisture content of the light and heat sensitive recording material after exposure and before development; and an optical fixing section that fixes the developed image by irradiating it with light. The image-recording apparatus can be a completely dry system that is capable of forming good print images without producing waste materials such as image transfer sheets. By controlling moisture content of the recording material, problems such as mottling of images can be prevented.

Abstract: An image-recording device that improves processing speed for image-recording that is carried out using a light and heat sensitive recording material. At the same time as irradiation of the light and heat sensitive recording material with light by a light source for fixing, a heating device heats the light and heat sensitive recording material. Because photo-fixing/photo-decolorization is carried out while the light and heat sensitive recording material is heated, viscosity of the system decreases, and dispersibility of active radicals increases. Due to this activation of radicals, a photopolymerization reaction and a photo-decolorization reaction accelerate, so that efficiencies of fixing and decolorizing increase.

Exposure is carried out by a plurality of LEDs provided at a light source section of an exposure unit of the light recording section.
