PROBLEM TO BE SOLVED: To vary an ink ejection amount along with a temperature change in a recording head. SOLUTION: The recording head is provided with a reference voltage source for setting an output voltage of a head drive power source, thereby providing a temperature characteristic of the voltage of the reference voltage source. A head drive power source circuit provided in the recording apparatus controls the output voltage by use of the reference voltage. COPYRIGHT: (C)2005,JPO&NCIPI
