Abstract
There are provided an image-forming method which is capable of improving image quality of a transfer image, and a transfer sheet film therefor, as well as an image-forming apparatus. An image is printed on at least one transfer sheet film provided for use on at least one of front and back surfaces of a print medium, by using sublimable dye ink, thereby causing the sublimable dye ink to be held in the transfer sheet film. The at least one transfer sheet film and the print medium are overlaid to each other such that a printing surface of the transfer sheet film faces the at least one surface of the print medium. The image is transferred by heating the transfer sheet film and the print medium overlaid to each other while applying pressure thereto and thereby causing diffusion of the sublimable dye ink held in the transfer sheet film in the at least one surface of the print medium for color development. Then, the transfer sheet film is removed from the print medium having the image formed thereon. The transfer sheet film is formed of a water-soluble and soft resin material, and the printing surface is formed to be a smooth surface.
