PROBLEM TO BE SOLVED: To provide such an image accepting sheet that even when severe temp. control is not performed for heating in the image forming process, an opaque detection mark is stably changed into transparent by heating, that the sheet can be easily and stably produced, and that the top or the back face of the image accepting sheet can be easily distinguished by an user to prevent troubles during carrying. SOLUTION: The image accepting sheet 8 has a detection mark 5, and the detection mark 5 is formed in such a manner that the mark is changed into transparent by heating and contains dispersion of a material which absorbs a specified wavelength region. Or, the detection mark 5 is changed into transparent by heating, and a layer 7 which absorbs a specified wavelength region may be formed under the detection mark layer 5. |
