A developing device according to the present invention comprises a turntable, a motor for rotating the turntable and a spraying nozzle for spraying mixture of developer and nitrogen gas onto the turntable in mist form. The turntable is rotated at a rotational speed of 200 rpm by driving the motor, the developer for developing the photoresist that has been formed on the upper surface of a semiconductor wafer fixed to the turntable is mixed with nitrogen gas, and the developer in mist form is sprayed from the spraying nozzle toward the turntable. The photoresist is surely removed due to the chemical reaction with the developer and the pressure of the spray of the developer.
