摘要： PROBLEM TO BE SOLVED: To provide a fixing unit having a cleaning web unit that does not cause the unnecessary feed of a web according to a change in the position of a pressure member.SOLUTION: A member 91 is freely rotatable about a fixed rotation shaft 26, has a square-hole shaped part 56 for holding the journal of the pressure roller 22 and fixing a distance between the shafts of the pressure roller 22 and the rotation shaft 26. The member 81 holds a slide bearing 57 in the square-hole shaped part 56 so that the slide bearing 57 is pressed to the pressure roller 22 by a compression spring 55. The slide bearing 57 is also pressed only in the direction of the pressure roller 22 in the square-hole shaped part 56. The slide bearing 57 presses a web contact roller 51 in the direction of the pressure roller 22. Even if the pressure roller 22 performs a pressure-reducing operation, the member 91 is only rotated and moved about the rotation shaft 26. Therefore, a positional relationship between the web contact roller 51 and the pressure roller 22 with respect to the member 91 and the vector of the pressing force of the web contact roller 51 as viewed from the pressure roller 22 are not changed.
