An image heating device is provided with a film having an electrical conductive layer, a magnetic flux generating unit. An eddy current is generated on the electrical conductive layer by the magnetic flux generated by the magnetic flux generating unit. The electrical conductive layer generates heat, and an image is heated by the heat of the film. The film is provided with an elastic layer arranged on the image side of the electrical conductive layer, and a primer layer is arranged between the electrical conductive layer and the elastic layer. It is possible to effectuate a heating fixation that can be started quickly with generating no nonuniformity in the image gloss and maintaining a high image quality.

A toner fixation film has an exothermic layer within which an eddy current is induced with application of a magnetic field and then heat is generated. The exothermic layer is a composite layer in which an exothermic part and resin part coexist. The toner fixation film can offer a sufficient heat generation necessary for toner fixation, and has enough flexiblity to permit curvature separation. A toner fixation apparatus comprises the toner fixation film and at least one coil for producing an alternating magnetic field for eddy current induction.

摘要:
A heat fixing belt having an electrically conductive layer in which an eddy current is produced by an alternating magnetic field applied from outside the belt thereby generating heat. The belt further includes toner release layer disposed on the surface of the fixing belt, the fixing belt being characterized in that the electrically conductive layer is an aluminum layer with a thickness less than 35 .mu.m, and having a rubber elastic layer between the aluminum layer and the toner release layer. The rubber elastic layer is disposed between the aluminum layer and the toner release layer making it possible to greatly reduce the time required to heat the fixing belt up to a predetermined temperature necessary for the fixing operation after the electric power is turned on. Thus, the invention can provide a heat fixing apparatus capable of quickly starting the fixing operation.

A fixing roller for thermally fixing an unfixed toner image is comprised of a core cylinder and a fluororesin tube fused on the core cylinder. The core cylinder is provided on its periphery with a minute groove means. On fusing the fluororesin tube on the core cylinder, the minute groove means gives to the surface of the fluororesin tube convexities or concavities extending in parallel in the peripheral direction of the fixing roller.

A sink device including a first data processing unit and a second data processing unit authenticates the processing units, when turned on, to generate first authentication keys having the same data. When a data request is issued from the sink device to the source device, device authentication is made between the source device and the first data processing unit to generate second authentication keys having the same data. The source device encrypts an exchange key using the second authentication key, and sends the encrypted exchange key to the first data processing unit. The first data processing unit decrypts the encrypted exchange key using the second authentication key, encrypts the decrypted exchange key using the first authentication key, and sends the encrypted exchange key to the second data processing unit. The second data processing unit decrypts the encrypted exchange key using the first authentication key to obtain an exchange key.
