Abstract: A fuser for thermally fixing a toner image on a recording medium includes: an endless fusing belt configured to transfer heat to the toner image; a heat source configured to heat the fusing belt; a detection unit configured to detect peripheral inward deformation of the fusing belt; and a power cut-off unit configured to cut off power supplied to the heat source upon detection of the peripheral inward deformation of the fusing belt by the detection unit.

Abstract: An image forming device includes: a developing device which includes a developing unit storing a developer containing a first carrier and a toner and a toner concentration detection unit detecting a toner concentration within the developing unit; and a supply container which stores a supply developer containing a second carrier and the toner, and supplies, based on a detection value by the toner concentration detection unit, the supply developer to the developing unit and discharges an excessive amount of the developer within the developing unit from the developing unit. Then, the setting value of the toner concentration detection unit is corrected based on the presence proportion of the second carrier within the developing unit detected by a calculation unit.
