Abstract:
1. A fuser comprising: a pressure application part that applies pressure to a medium for forming a print image; an annular body that is rotatably supported for carrying the medium in a manner that the medium is sandwiched between the annular body and the pressure application part for applying heat to the medium for forming the print image; a fuser part heat generation body that is arranged on an inner side of the annular body for generating heat to apply heat to the annular body; a first temperature detection end that is arranged in contact with one end part outside a medium carrying corresponding range of a surface of the annular body and detects temperature of the annular body outside the medium carrying corresponding range, the medium carrying corresponding range being a range in which the medium is carried; a heat generation interruption part that, in response to the temperature of the annular body that is detected via the first temperature detection end, interrupts heat generation of the fuser part heat generation body; and a reflection part that is arranged on an inner side of the annular body, and reflects radiant heat of the fuser part heat generation body toward at least the medium carrying corresponding range of the annular body and the one end part.
