Fixing device and image forming apparatus
A fixing device includes a heating member, a detector, a holding member, and a biasing member. The heating member is configured to transport a recording medium while nipping the recording medium with a pressure member, so as to fix a toner image onto the recording medium. The detector is configured to measure a temperature of the heating member. The holding member holds the detector. The biasing member biases the holding member so as to bring the detector into contact with a surface of the heating member.
