A heat-sensitive recording method of performing a thermal printing at variable printing time intervals by a thermal head in a facsimile apparatus. The method includes the steps of determining a pulse width corresponding to a thermal head temperature, from a measured resistance of a thermistor measured at a first time interval, on the basis of a relationship between thermal head temperature and pulse width, storing the determined pulse width corresponding to the temperature in a first memory area and storing a recording power pulse width corresponding to the pulse width in a second memory area, and correcting the recording power pulse width on the basis of a relationship between thermistor resistance and thermal head temperature by changing the recording power pulse width at a second time interval by comparing the same with the pulse width, so that a thermal printing is performed in which the recording power pulse width is varied in gradual steps by applying a printing power pulse with the thus corrected pulse width to the thermal head.
