摘要
An image forming apparatus including: a fixer that fixes a toner image formed on a recording medium by pressing and heating the recording medium nipped in a nip portion formed by causing two rotating bodies to pressedly abut on each other, and conveying the recording medium by rotating the rotating bodies; a motor that drives the rotating bodies by transmitting a torque to at least one of the rotating bodies; a torque detector that detects the torque transmitted to the rotating body by the motor; a temperature detector that detects temperature of the rotating body; a speed detector that detects a conveyance speed for conveying the recording medium by the fixer; and a controller that corrects the detected torque based on at least any one of the detected temperature and the detected conveyance speed and predicts a life of the fixer based on the corrected torque.
