A high-voltage generator includes a high-voltage unit (1) and a further voltage generating unit (2) for generating DC high voltages (UF1, UF2), the voltage generating unit (2) including an adjustment unit (3) for adjusting a DC high-voltage (UF1, UF2) in an adjusting range between a lower and an upper limit voltage. In order to enable an as low as possible electric strength of the adjustment unit (3) and to reduce the impedance of the voltage generating unit (2), a DC voltage of between 100% and 200% of the upper limit voltage is applied to one connection point of the adjustment unit (3) whereas a DC voltage of between 50% and 100% of the lower limit voltage is applied to the other connection point of the adjustment unit (3).
