PROBLEM TO BE SOLVED: To precisely measure an amount of ejected ink even when a scanner or CCD camera having a low resolution is used in an inexpensive system. SOLUTION: This method for measuring an amount of ejected ink of an inkjet recording head comprises a relationship table forming process of forming a relationship table indicating a relationship of a value of a drive voltage, the number of pixels and an amount of ejected ink, a drive voltage sweep process of varying the value of the drive voltage from a first drive voltage measurement value which is the value of the drive voltage at the time when the number of pixels measured in a pixel number measurement process is a first pixel number to a second drive voltage measurement value which is the value of the drive voltage on a boundary time point while the number of pixels measured in the pixel number measurement process is changed from the first pixel number to the second pixel number, and an ink ejection amount computing process of computing the amount of ejected ink at a time when the drive voltage in the first drive voltage measurement value determined from the relationship table by using the first drive voltage measurement value and the second drive voltage measurement value.
