Temperature is detected by a temperature sensor disposed near a recording head. When the detection result is a temperature that is higher than room temperature, an appropriate movement amount of the recording head is calculated from a relation between response speed of the temperature sensor and a LED light amount, and a moving speed of the recording head is controlled. When the result of the detection by the temperature sensor is a temperature that is lower than room temperature, an appropriate exposure amount is calculated from the relation between the response speed of the temperature sensor and the LED light amount, and the amount of light emitted by LEDs is controlled.
