Abstract

Provided is a static eliminator capable of holding ion balance uniform regardless of a distance from the static eliminator. The static eliminator includes: an electrode driving device that alternately and repeatedly applies, to a discharge electrode, a positive drive voltage and a negative drive voltage as drive voltages for corona discharge; decreases a ratio of the application time of the positive drive voltage while relatively increasing the voltage value of the positive drive voltage in a case of increasing positive ions, and increases the ratio of the application time of the positive drive voltage while relatively decreasing the voltage value of the positive drive voltage in a case of increasing negative ions.
