Abstract
A fixing apparatus includes a fixing device configured to, by allowing a sheet having a developing agent image on it to pass between a heating roller and a pressing roller set in contact with the heating roller, fix the developing agent image in which at least one of the heating roller and pressing roller is configured to have an inner elastic layer and a conductive layer formed on a surface side of the elastic layer and the elastic layer is bonded to the conductive layer by a heat-resistant adhesive having a heat-resistant temperature of over 200° C.

(canceled).
A fixing apparatus comprising:
- a fixing device configured to, by allowing a material to be fixed having a developing agent image to pass between a heating rotation body and a pressing rotation body set in contact with the heating rotation body, fix the developing agent image, wherein at least one of the heating and pressing rotation bodes comprises an elastic rotation body having a core member, an elastic layer formed on a surface of the core member and a conductive layer formed on a surface side of the elastic layer;
- a drive device configured to rotate the elastic rotation body by giving a rotation drive force to the core member of the elastic rotation body;
- a detection device configured to detect a difference between rotation speeds of the surface portion and the core member at a rotation time of the elastic rotation body;
- and
- a determination device configured to determine that a failure has occurred based on the difference detected by the detection device.
A fixing apparatus comprising:
- a fixing device configured to, by allowing a material to be fixed having a developing agent image to pass between a heating rotation body and a pressing rotation body set in contact with the heating rotation body, fix the developing agent image and wherein at least one of the heating and pressing rotation bodies is comprised of an elastic rotation body having a core member, an elastic layer formed on the core member and a conductive layer formed on the elastic layer;
- a drive device configured to rotate the elastic rotation body by giving a rotation drive force to the core member of the elastic rotation body;
- and
- a detection device configured to detect a difference between rotation speeds of a surface portion and a core portion of the elastic rotation body at a rotation time,
- wherein the detection device has a detection roller configured to be rotationally driven by the rotation of the elastic rotation body and detect a peripheral speed of a surface of the elastic rotation body by measuring the rotation speed of the detection roller.
