ABSTRACT:
A thermal transfer recording apparatus which performs image recording by causing a recording head to act on an ink sheet so as to transfer ink from the ink sheet onto recording paper. Changes in the take-up amount of the ink sheet, which is fed by being wound onto a take-up roller, are detected from changes in the amount by which the ink sheet is fed with respect to a given drive amount of an ink-sheet feeding motor, and, on the basis of the changes detected, the driving torque for the ink-sheet feeding motor is changed, thereby reducing the noise generated and the power consumed by the apparatus.
