Fixing device and image forming apparatus

An image forming apparatus including a fixing device for thermally fixing an unfixed image formed on a recording sheet by passing the recording sheet through a fixing nip, the fixing device comprising:

• a heat-generating endless belt having, on a circumferential surface thereof, a sheet passing area through which the recording sheet passes;
• a first pressure member disposed inside a running path of the heat-generating endless belt;
• and
• a second pressure member disposed to press the heat-generating endless belt against the first pressure member from outside the running path to form the fixing nip, wherein
• the heat-generating endless belt includes:
• a resistive heat layer that generates heat upon having electric current applied thereto;
• and
• a pair of electrode layers that receive electric current, the electrode layers flanking the sheet passing area, and
• the resistive heat layer is in contact with the electrode layers at a different one of end faces opposing each other in a width direction of the resistive heat layer.
