Abstract
An ion generating apparatus, comprising: an ion generating circuit including a positive ion generating electrode pair and a negative ion generating electrode pair; and a controller configured to control the ion generating circuit, wherein the controller causes the ion generating circuit to apply a positive voltage to the positive ion generating electrode pair and a negative voltage to the negative ion generating electrode pair in different periods, the positive voltage having a waveform that is a first ringing voltage waveform a negative peak of which is removed, and the negative voltage having a waveform that is a second ringing voltage waveform a positive peak of which is removed.
