PROBLEM TO BE SOLVED: To provide a new reimageable medium for recording desired images. SOLUTION: The reimageable medium is composed of a substrate and a photochromic material, wherein the medium has a characteristic that when the medium exhibits the absence of a color contrast and is then exposed to an imaging light to result in an exposed region and a non-exposed region, the color contrast is present between the exposed region and the non-exposed region to form a temporary image corresponding to a predetermined image that is visible for a visible time, wherein the medium has a characteristic that when the temporary image is exposed to an indoor ambient condition for an image erasing time, the color contrast changes to the absence of the color contrast to erase the temporary image, and wherein the medium is capable of undergoing multiple cycles of temporary image formation and temporary image erasure.
