Abstract
A method for uniformly erasing an image recorded on a thermo-reversible recording medium. The image erasing apparatus includes an LD array, which emits a laser light whose cross section has a line shape; optics which include at least one cylindrical lens which converts, into a converging light which converges in a width direction, a line-shaped laser light which is emitted from the LD array and emits the converging light; and a mono-axial galvano mirror which deflects the laser light emitted from the optics in the width direction to scan the deflected laser light onto the thermo-reversible recording medium.
