Abstract:
1. A fixing device, comprising: a rotary member for transporting printing paper; a pressure member for press-contacting the rotary member to apply pressure onto the printing paper; and at least one cleaning member capable of freely moving into contact with, or away from, a peripheral surface of the rotary member and/or a peripheral surface of the pressure member, wherein a toner image formed on the printing paper is fixed while the printing paper is being held between the rotary member and the pressure member, said fixing device further comprising: a contact and separation unit for moving the pressure member into contact with, or away from, the rotary member; a press roller for pressing the cleaning member; and a roller biasing member for biasing the press roller in a bias direction intersecting with contact and separation directions in which the cleaning member moves into contact with, or away from, the rotary member, wherein: the cleaning member moves into contact with, or away from, the peripheral surface of the rotary member and/or the peripheral surface of the pressure member in conjunction with the contact and separation unit moving the pressure member into contact with, or away from, the rotary member; the cleaning member is supported to reciprocate freely in the contact and separation directions, is capable of freely moving into contact with, or away from, the peripheral surface of the rotary member, and moves into contact with, or away from, the rotary member in conjunction with the contact and separation unit moving the pressure member into contact with, or away from, the rotary member; and the press roller biases the cleaning member, separated from the rotary member, in one of the contact and separation directions in which the cleaning member moves away from the rotary member.
