发明名称 Image forming method exerting joule heat on an irradiated portion of a photoconductive layer, and an apparatus used for such a method
摘要 An image-forming method using a latent-image forming body which consists of a transparent electrode layer, a photoconductive layer, an electrode layer and a pyroelectric-material layer made of a dielectric substance that are successively stacked on its transparent base. In this method, conductive carriers are generated in the photoconductive layer by irradiating information light thereto by using a light source that is placed at a location opposite to the transparent base. Then, heat is exerted at the light-irradiation portion of the photoconductive layer by applying a voltage across the transparent electrode layer and the electrode layer, and the heat causes a temperature rise in the pyroelectric-material layer such that an electrostatic latent image is formed by the pyroelectric effect. The electrostatic latent image is developed by allowing the developer, charged to have the polarity reversed to that of the electrostatic latent image, to be attracted by the electrostatic latent image. Thus, the image-forming method requires neither a heater such as an expensive thermal head, nor a charger used for the latent-image forming body, and also does not use expensive developer having conductivity and magnetism. This makes it possible to form images at low costs.
