Abstract
An image recording apparatus includes a recording unit that records an image in a first region, a first control unit that has a drive roller to transport a recording medium and controls a tension of the recording medium in the first region by adjusting a torque of the drive roller based on the tension of the recording medium in the first region, a second control unit that controls the tension of the recording medium in a second region according to the detection result of the tension of the recording medium in the second region. Compared to the frequency response characteristics of the first control unit with respect to the tension fluctuations generated in the first region, the frequency response characteristics of the second control unit with respect to the tension fluctuations generated in the second region responds to the tension fluctuations having a higher frequency band.
