Abstract
In a device for recycling a recording medium by removing a film-like image forming substance from the medium, a separating member contacts one side of the medium carrying the substance. The separating member is durable because its surface contacting the medium is provided with a measure against deterioration. Anticorrosion means reduces the deterioration rate of the separating member.
Claims24
A device for removing a film-like image forming substance from a recording medium having a swelling layer, which swells with a water-containing image removal promoting liquid, at least in the vicinity of a surface where an image is to be formed, said device comprising:
- applying means for applying said image removal promoting liquid to the recording medium on which an image is formed by the image forming substance, to thereby cause the swelling layer to swell more than the image forming substance;
- separating means comprising a separating member for separating the image forming substance from the recording medium by being pressed against said recording medium to which said image removal promoting liquid has been applied;
- at least a surface of said separating member that contacts the recording medium being formed of a metallic material;
- and
- electric potential control means for maintaining an electric potential of said separating member lower than an anticorrosion potential of said metallic material.
A device for removing a film-like image forming substance from a recording medium having a swelling layer, which swells with a water-containing image removal promoting liquid, at least in the vicinity of a surface where an image is to be formed, said device comprising:
- applying means for applying said image removal promoting liquid to the recording medium on which an image is formed by the image forming substance, to thereby cause the swelling layer to swell more than the image forming substance;
- and
- separating means comprising a separating member for separating the image forming substance from the recording medium by being pressed against said recording medium to which said image removal promoting liquid has been applied;
- at least a surface of said separating member that contacts the recording medium being formed of a metallic material, wherein said metallic material comprises at least one metallic element selected from a group consisting of Fe, Co, Ni, Al, Cr, Au, Ag, Cu, and an alloy containing said at least one metallic element.
