Abstract:
1. A fixing device comprising: a hollow fixing body configured to rotate and generate heat to heat an unfixed image carried by a sheet; a pressing body configured to rotate in press contact with the fixing body and add a pressure to the sheet; a pushing member configured to push the fixing body against the pressing body from an inner side of the fixing body and slide on the inner side of the fixing body; and a power supply unit configured to supply electric power for causing the fixing body to generate heat, wherein the fixing body is formed by stacked layers including a first heating layer, a second heating layer, and an insulation layer interposed between the first heating layer and the second heating layer, wherein two electrodes of the power supply unit are configured to connect to the first heating layer and the second heating layer at one end portion of the fixing body in a rotation axis direction, wherein the first heating layer and the second heating layer are connected by an electrical conducting member arranged in the fixing body at the other end portion of the fixing body in the rotation axis direction, and wherein a current supplied from the power supply unit flows through one of two electrodes, the first heating layer, the electrical conducting member, the second heating layer and the other of the two electrodes.
