Abstract:
1. A fixing device which is detachably provided in a main body of an image forming apparatus for forming an image on a recording medium, and applies heat and pressure to a toner image borne on the recording medium to fix the toner image onto the recording medium, the fixing device comprising: a first fixing member; a heating section having a heat generating layer including a heat generating resistor which generates heat due to electrical conduction; a fixing belt which is an endless belt member, the fixing belt being supported around the first fixing member and the heating section with tension; a second fixing member provided to be opposite to the first fixing member with the fixing belt interposed therebetween; a temperature detection element which detects a temperature of a surface of the fixing belt; a control section which controls electrical conduction to the heat generating resistor on a basis of the temperature detected by the temperature detection element such that a surface temperature of the fixing belt is at a predetermined temperature; and a connector which connects the heat generating resistor and the temperature detection element to the control section, the connector comprising integrally primary-side wiring connector terminals to be connected to primary-side wires each leading to the heat generating resistor, and secondary-side wiring connector terminals to be connected to secondary-side wires including wires each leading to the temperature detection element, the secondary-side wires flowing current smaller than the primary-side, wherein the connector is arranged such that the primary-side wiring connector terminals are sandwiched between the secondary-side wiring connector terminals, and when it is detected that there is a connection fault between the secondary-side wires and the secondary-side wiring connector terminals, the control section controls such that electrical conduction to the heat generating resistor is suppressed.
