Abstract: Disclosed in a control method of a clothes dryer. The drying method of a clothes dryer, includes: detecting a temperature of the air exhausted from a drum; determining a change in water content of a drying material on the basis of the detected temperature; and controlling a drying operation according to the water content change of the drying material. Accordingly, the air temperature in an exhaust port of a drum is measured, and a water content or a temperature of a drying material can be determined on the basis of data about a gradient of the temperature change.
