摘要：
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 SP p , the SP value of the substance constituting the surface of the recording medium is taken as SP m , and the SP value of the substance constituting the surface of the image erasing means is taken as SP c , said SP p , SP m and SP c satisfy the relationship |SPp - SPm| > |SPp - SPc|.
