Zusammenfassung:	PROBLEM TO BE SOLVED: To solve a problem in which: it has been difficult to drive a plurality of piezoelectric transformers with single control to raise voltage, since each of the piezoelectric transformers has different input and output characteristics due to variation during the manufacture.SOLUTION: A high-voltage power supply device 90 includes frequency dividing means 817, driving means 93, a piezoelectric transformer 91, output means (94, 95), frequency division ratio output means 812, a first correction value storage table 825, correction value storage means 826, and calculating means (814, 815, 816). Accordingly, the high-voltage power supply device that includes a plurality of piezoelectric transformers each having different input and output characteristics can be driven with single control to raise voltage.
