PURPOSE:To obtain an image with high durability without using a camera, by a method wherein the shape or pattern of an object to be photographed is transferred as a toner image onto a photographic paper film coated with a gelatinous layer by dry-type copying, followed by exposure and development. CONSTITUTION:The photographic paper film is processed as a copying paper by a dry-type copying machine. Onto the gelatinous layer 12 applied to a base 11, the image of the object to be photographed is transferred as a toner image formed of a toner 13. The paper film thus treated is subjected to a fixing treatment using an ordinary photographic fixing liquid, whereby a silver salt is dissolved away from the gelatinous layer 12 at parts other than the part coated with the toner 13. After washing with water, the toner 13 is released by a solvent such as a thinner or an adhesive tape. The part from which the toner 13 has been released has not been desilvering. Then, printing is conducted, whereby the part corresponding to the transferred image is turned black, resulting in obtaining a black positive film. |
