PROBLEM TO BE SOLVED: To provide a print head, a method of driving the print head and a printer capable of stabilizing energy to be supplied to each ejection nozzle irrespective of fluctuation of a voltage of a power supply and variation of the number of the ejection nozzles and of adequately ejecting ink even when the many ejection nozzles are used. SOLUTION: A current is supplied to each of resistors R1-Fn each for supplying energy to the respective nozzles from respective transistors Tr14-Tr (n+13) which are constant current sources.
