ABSTRACT:
In a thermal transfer recording apparatus, an image is recorded on a recording medium by transferring ink of an ink sheet. The ink sheet is wound onto a wind-up roll from a feed roll against an applied load. During the recording process the ink sheet and recording medium are conveyed in opposite directions. After recording of one page is completed, the recording medium is advanced, cut, and then retracted. During advancement of the recording medium to the cutter, the ink sheet is wound onto the wind-up roll at a speed such that the ratio of conveyance speeds of the ink sheet and recording medium is greater than during recording. During retraction of the recording medium, the ink sheet is conveyed by friction with the recording medium in a direction opposed to the load.
