Abstract
A fixing device includes a heat member, a belt member, a belt support member, a first rotation member, a second rotation member, and a separation contact mechanism. The belt member is heated by the heat member. The belt support member operably supports the belt member. The first rotation member tightly stretches the belt member with the belt support member. The second rotation member is disposed opposite to the first rotation member through the belt member. The separation contact mechanism makes the heat member to contact the belt member when the first rotation member rotates, and makes the heat member separate from the belt member when the first rotation member halts.
Claims8
A fixing device comprising:
- a heat member;
- a belt member heated by the heat member;
- a belt support member operably supporting the belt member;
- a first rotation member tightly stretching the belt member with the belt support member;
- a second rotation member disposed opposite to the first rotation member through the belt member and pressed against the first rotation member;
- and
- a separation contact mechanism making the heat member contact the belt member when the first rotation member rotates and making the heat member separate from the belt member in a state that tension of the belt member is maintained when the first rotation member halts.
An image forming apparatus comprising an image forming unit for forming an image and a fixing device for fixing the image formed at the image forming unit, the fixing device comprising:
- a heat member;
- a belt member heated by the heat member;
- a belt support member operably supporting the belt member;
- a first rotation member tightly stretching the belt member with the belt support member;
- a second rotation member disposed opposite to the first rotation member through the belt member and pressed against the first rotation member;
- and
- a separation contact mechanism making the heat member contact the belt member when the first rotation member rotates and making the heat member separate from the belt member in a state that tension of the belt member is maintained when the first rotation member halts.
