Patent ID: 6845225

Claim:
A cleaning sheet adapted to clean a surface of a heating roll in a fixing device, which causes a recording sheet bearing a toner image formed of a magnetic toner containing a magnetic material to pass through the fixing device under a state in which the recording sheet is in press contact with the surface of the heating roll having arranged thereon a contact component in contact with the surface of the heating roll and heated to a fixing temperature to rotate, to perform fixing of the toner image, comprising a synthetic resin sheet with a thickness of 100 μm or more, which is made of a thermoplastic resin with a melting point higher than the fixing temperature and Rockwell hardness of M60 or more or thermosetting resin with Rockwell hardness of M60 or more, the sheet passing through the fixing device under a state of being in press contact with the surface of the heating roll to thereby remove an aggregate mainly containing the magnetic material adhering to the surface of the heating roll.
