In a regenerating method and apparatus of a recorded material in which at least a portion of the recorded material in the vicinity of a surface thereof on an image forming side is wet and expands with a liquid, the wet and expanding liquid (also called an image removing accelerating liquid in the following description) is provided to the recorded material so that the portion of the recorded material in the vicinity of the surface thereof is wet and expands with this liquid. A separating member comes in contact with an image forming substance having a film shape and a thermoplastic or thermally melted property and formed in the vicinity of the surface of the recorded material in a state in which joining force between the image forming substance and the recorded material is reduced. An image in the vicinity of the surface of the recorded material is transferred onto the separating member so that the image forming substance on the recorded material is removed therefrom. The image removing accelerating liquid is provided to the same recorded material plural times.
