Abstract: The fixing device includes a cylindrical heated member and a heating part. The cylindrical heated member is long in a width direction of a sheet, and is supported in a rotatable manner with coming into contact with a fixing face of the sheet. The heating part is provided in an inner space of the heated member and heating an inner circumferential face of the heated member. The heating part includes a plurality of heaters disposed side by side in a longitudinal direction of the heated member; and a first temperature sensor measuring a first heater of the plurality of heaters or a heated area of the heated member heated by the first heater. The plurality of heaters and the first temperature sensor are connected in series by a first power supply line.

Abstract: A fixing device includes a fixing belt, a pressure roller, and a plurality of heaters. The pressure roller is provided in contact with an outer peripheral surface of the fixing belt. The plurality of heaters are each flat-plate and arranged in line along a running direction of the fixing belt to be pressed against an inner peripheral surface of the fixing belt, and the flat-plate heaters are arranged in a positional relation where a peak of a nip pressure of a nip region is downstream of a center of the nip region in the running direction of the fixing belt, the nip region being a region where the fixing belt and the pressure roller are in contact with each other.
