In a color thermal transfer recorder, L is set to a distance from a printing position to first and second sensors for detecting each of marks, q is set to a pitch between the marks, N is set to an integer equal to 2 or more, S is set to an arbitrary value from zero to the pitch q, and delta is set to an arbitrary value from 0 to 4 mm. The values L, q, N, S and delta are set such that the following formula L=Nxq+S+ delta is satisfied. The values L, q, N, S and delta may be set such that the following formula L=Nxq+S- delta is satisfied. In this recorder, various kinds of marks are formed on an ink sheet and are detected by the first and second sensors so that a conveying operation of the ink sheet is controlled. In accordance with this structure of the recorder, the distance from the printing position to the first and second sensors is increased so that a degree of freedom in design of the recorder is increased.
