The present invention includes a bibliographic information and identification information such as a face photograph, has a watermark pattern that exhibits gradation, has excellent continuous tone full-color images and various images with metallic luster on both sides, and has high design properties. And an image forming method capable of forming on-demand an image forming product having high visibility and high durability. A transparent substrate has a portion in which two white layers are laminated and a portion in which a concealing layer is laminated between the two white layers on at least one side of the transparent base material, depending on the presence or absence of the concealing layer. In the image forming method, a transparent image is formed by expressing gradation by the size of the area to which the concealing layer is transferred. In the obtained image formed product, the whiteness of the portion where the two white layers are laminated is 40% or more and the total light transmittance is 30 to 75%, and the concealing layer is provided between the two white layers. The whiteness of the laminated portion is 40% or more and the total light transmittance is 0.3 to 30%. [Selection] Figure 1 |
