Abstract
A temperature detection device includes first and second temperature detection units configured to detect first and second temperatures, respectively, of a first roller at first and second positions in an axis direction, heated by a central heating unit and an end part heating unit; third and fourth temperature detection units configured to detect third and fourth temperatures, respectively, of a second roller which can be in pressure-contact with the first roller, at the first and second positions; and a control unit configured to control the heating units. The control unit determines a state of at least one of the first, second, third and fourth temperature detection units based on a comparison between first and third rise rates of the first and third temperatures, respectively, or on a comparison between second and fourth rise rates of the second and fourth temperatures, respectively.
