    • There is provided an image display apparatus and an image erasing method, by which a color image made of an ink can be displayed by fixing the ink on the recording medium, and, when it is desired to erase the color image, the color image on the recording medium can be erased by image erasing means. Therefore, the present invention comprises ink application means 1 for applying an ink onto recording medium 10 in accordance with image data, and image erasing means 4 for erasing the image formed on recording medium 10 by ink application means 1, wherein, when the solubility parameter (SP value) of the substance remaining on recording medium 10 after applying the ink is taken as SPp, the SP value of the substance constituting the surface of the recording medium is taken as SPm, and the SP value of the substance constituting the surface of the image erasing means is taken as SPc, said SPp, SPm and SPc satisfy the relationship |SPp−SPm|>|SPp−SPc|.
    • 提供了一种图像显示装置和图像擦除方法,通过该图像显示装置和图像擦除方法,可以通过将油墨固定在记录介质上来显示由墨制成的彩色图像,并且当需要擦除彩色图像时,彩色图像在 可以通过图像擦除装置擦除记录介质。 因此,本发明包括根据图像数据将油墨施加到记录介质10上的油墨施加装置1和用于通过油墨施加装置1擦除在记录介质10上形成的图像的图像擦除装置4,其中当溶解度参数 将施加墨后的残留在记录介质10上的物质的SP值作为SPp,将构成记录介质表面的物质的SP值作为SPm,构成表面的物质的SP值 将图像擦除手段作为SPc,则SPp,SPm,SPc满足关系| SPp-SPm |> | SPp-SPc |。
