PURPOSE:To provide an image erasing method capable of keeping high contrast without lowering image density at the time of the formation of an image even if the formation and erasure of an image are repeated. CONSTITUTION:In an image erasing method heating a display medium composed of a reversible thermal recording material wherein a thermal recording layer capable of forming and erasing an image by heating is provided on a support to erase an image, erasing energy is set to high energy equal to or more than the center value of a transparentizing energy range at the time of the erasure of the image on the display medium and the display medium is heated by a contact pressing type or non-contact type heating means to erase an image. |
