Abstract:
An image forming device includes: a fixing device that includes a fixing rotary member and thermally fixes a toner image onto a recording sheet by the fixing rotary member; a temperature sensor that senses a temperature of the fixing rotary member as a fixing temperature; a driving unit that drives the fixing rotary member to rotate; a torque sensor that senses a torque value of the driving unit in a torque sensing period in which at least one of the fixing temperature and a driving speed falls within a predetermined range, the driving speed being a speed of the driving unit for driving the fixing rotary member to rotate; and a prediction unit that predicts an operating life of the fixing device based on the sensed torque value.

Claim (Index 2):
The image forming device of  claim 1 , further comprising:\n a temperature controller that controls the fixing temperature to fall within a range suitable for thermal fixing of toner images; and a speed controller that controls the driving unit such that the driving speed falls within a range suitable for thermal fixing of toner images, wherein the torque sensing period is a period in which the temperature controller and the speed controller respectively control the fixing temperature and the driving speed to fall within the respective predetermined ranges, except a period in which the driving speed varies due to start and end of pressure-contact between the recording sheet and the fixing rotary member.
