Abstract
A fixing device includes a rotating member, a bearing and a heat insulating member. The rotating member fixes a toner image onto a recording medium. The bearing rotatably supports the rotating member. The heat insulating member is interposed between the rotating member and the bearing and rotated around a rotation axis. A notch part is arranged in a portion in a circumferential direction of the heat insulating member so as to continue from an end part at an inside to an end part at an outside in a direction of the rotation axis. At least one groove part is formed in a contact portion with the rotating member or the bearing in a circumference face of the heat insulating member.
