A fixing portion is provided with a fixing roller, a heating roller having a heat source, a fixing belt stretched between the fixing roller and the heating roller, and a pressurizing roller that is brought into pressure contact with the fixing roller across the fixing belt and forms a nip portion into which a sheet of paper is conveyed between the fixing belt and the pressurizing roller. The fixing portion is further provided with a pad that has a contact surface portion in contact with the inner peripheral surface of the fixing belt, and a biasing member that biases the pad in a direction in which the contact surface portion is brought into pressure contact with the inner peripheral surface of the fixing belt. The pad is configured so as to pivot about the rotating shaft of the heating roller.

Fixing device and image forming apparatus

Vacuum heat insulator comprising a laminated core made of a plurality of sheets of inorganic fibers having 10 &#x3bc;m or smaller in diameter and a certain composition including SiOas a main component, AlO, CaO, and MgO, a gas barrier enveloping member, and an absorbent. The vacuum heat insulator is characterized by having at least one groove formed therein after fabrication of the vacuum heat insulator. Further, the vacuum heat insulator is characterized by using inorganic fiber core of which a peak of distribution in fiber diameter lies between 1 &#x3bc;m or smaller and 0.1 &#x3bc;m or larger, and not containing binding material for binding the fiber material. Electronic apparatuses use the vacuum heat insulator. With use of the vacuum heat insulator, electronic and electric apparatuses superior in energy saving and not to present uncomfortable feeling to the user can be provided.
