Claim:
1. A high-voltage power unit for selectively outputting a high voltage having a positive or negative polarity, the high-voltage power unit comprising: a positive voltage generating unit for generating a positive high voltage; a negative voltage generating unit for generating a negative high voltage; a first load unit connected between a pair of output terminals of the positive voltage generating unit; and a second load unit connected between a pair of output terminals of the negative voltage generating unit, wherein one of the pair of output terminals of the positive voltage generating unit is connected to one of the pair of output terminals of the negative voltage generating unit to connect the two voltage generating units in series, any of another of the pair of output terminals of the positive voltage generating unit and another of the pair of output terminals of the negative voltage generating unit is defined as a reference side, while a high-voltage output whose polarity is switched is taken out from the another terminal defined as the reference side, and the high-voltage power unit further comprises:
