The object of the present invention is to provide a thermoreversible recording medium which possesses not only such an excellent property that the electrostatic charge on the thermoreversible recording medium can be prevented and the curling of the thermoreversible recording medium caused by repeating heating for the printing and erasing of the thermoreversible recording medium can be also prevented, but also an excellent conveyability which is not affected by repeating the use of the thermoreversible recording medium and by an using condition thereof. For attaining the object, the present invention provides a thermoreversible recording medium comprising a support, a thermosensitive layer disposed on the support which reversibly changes the color depending on the temperature, a protective layer disposed on the thermosensitive layer, and a back layer disposed on a surface of the support which is opposite to another surface of the support on which the thermosensitive layer is disposed, wherein the back layer comprises a needle-like conductive filler.
