Abstract
A method and apparatus for forming an image using an image forming sheet that is normally non-photosensitive but can be rendered photosensitive by preheating and is exposed at the preheated area to a light image to form therein a latent image and then heat-developed to form a visible image. After preheating, the preheated area is cooled by cooling means prior to exposure.
Claims12
In an image forming method for forming a visible image using an image forming sheet containing at least an organic silver salt oxidizing agent, a reducing agent for silver ion and a binder, which sheet is normally non-photosensitive but can be rendered photosensitive by preheating prior to exposure;
- and wherein said image forming sheet is preheated to render it photosensitive, is exposed to a light image to form therein a latent image and then is heat-developed to form a visible image;
- the improvement comprising, after preheating an area of the image forming sheet, the step of cooling said area of the image forming sheet to a temperature below 60.degree. C. prior to exposure.
