Claims

[Scope of utility model registration request]

It has a back-up roll, a hot roll that rotates following the drive rotational force of the back-up roll, and a peeling claw that peels off the printing paper attached to the surface of the hot roll, and presses the printing paper against the surface of the hot roll. In the fixing device that fixes the unfixed image to the printing paper, if the unfixed image is within a predetermined area from the leading edge of the printing paper, the tip of the peeling claw is brought into contact with the surface of the hot roll. A fixing device comprising: a driving mechanism for the peeling claw, which causes the peeling claw to be in contact with the surface of the hot roll at other times;
