<p>An image processing method including at least one of recording an image onto a thermoreversible recording medium in which transparency or color tone reversibly changes depending upon temperature, by applying a laser beam with the use of a CO 2 laser device so as to heat the thermoreversible recording medium, and erasing an image recorded on the thermoreversible recording medium, by heating the thermoreversible recording medium, wherein the intensity distribution of the laser beam applied in the image recording step satisfies the relationship represented by Expression 1, 1.59 < I 1 / I 2 ‰¤ 2.00
where I 1 denotes an irradiation intensity of the applied laser beam in a central position of the applied laser beam, and I 2 denotes an irradiation intensity of the applied laser beam on a plane corresponding to 80% of the total irradiation energy of the applied laser beam.</p> |
