In a heat transfer recording apparatus for printing images on recording paper by bringing ink film in contact with recording paper and heating them by means of a thermal head, the preheating time of the thermal head is decided based on the thermal head temperature detected by a thermistor and the accumulated power supply time obtained as a product of the number of times power is supplied to the thermal head and the detection interval, thus to achieve a uniform image quality by eliminating the effect of the thermal head heat accumulation even in case of forming multiple images successively on multiple sheets of recording paper.
