ABSTRACT:
An image forming apparatus stores inside a light-shielding container a photosensitive sheet having a surface coated with microcapsules encapsulating a light-curable agent and a colorless dye. After this photosensitive sheet is pulled out of the container and exposed to image-forming light to form a latent image thereon, an image transfer sheet having one surface coated with a developing agent having an chromogenic effect on the encapsulated colorless dye is superposed on the photosensitive sheet and pressed together to selectively rupture unhardened ones of the microcapsules. After a jam detected inside the apparatus is removed, double exposure of the microcapsules is prevented by advancing the photosensitive sheet by an appropriate distance depending on whether exterior light is detected by sensors inside the apparatus and whether the jam occurred during an image forming operation.
