  • Patent number: 6128464
    Abstract: An apparatus according to the present invention removes printing material from a recording member on which an image is recorded by the printing material. The apparatus includes a releasing member and a separation member. The releasing member comes into pressure contact with the recording member and adheres to the printing material on the recording member. The separation member separates the recording member from the releasing member at a separation point and releases the printing material from the recording member by bending the releasing member and the recording member in mutually opposite directions so as to make the radius of curvature of the recording member smaller than the radius of curvature of the releasing member.
