Abstract
The present invention provides a fixing apparatus including: a pair of rotating bodies that transports a recording medium on which an image is formed by using an image forming material, by sandwiching the recording medium; a heating section that heats at least one of the pair of rotating bodies; a moving section that moves the pair of rotating bodies between a position at which they mutually contact and a position at which they are mutually separated; a temperature detecting section that detects a surface temperature of at least one of the pair of rotating bodies without contacting the rotating bodies; and a twine generation determining section that determines whether the recording medium has twined around either one of the pair of rotating bodies based on a rate of temperature increase after a temperature decrease of the surface temperature detected by the temperature detecting section.
