Abstract
A fixing device has a presser member, a slide member and a pressure belt. Both ends of the presser member are positioned outside both ends of the slide member. Both ends of the slide member are positioned outside both ends of the pressure belt. Thereby, the slide member and the pressure belt are improved in service life, so that the fixing device as a whole is improved in service life.

A fixing device comprising:
- a heating rotation unit and a pressure rotation unit which rotate together in mutual contact;
- a heating section for heating the heating rotation unit;
- a presser member placed inside the pressure rotation unit to press the pressure rotation unit toward the heating rotation unit;
- and
- a slide member placed between the pressure rotation unit and the presser member and slid in contact with an inner surface of the rotating pressure rotation unit, wherein
- both ends of the presser member are positioned outside both ends of the slide member, and both ends of the slide member are positioned outside both ends of the pressure rotation unit with respect to an axial direction of the heating rotation unit.
