Abstract:
1. A static eliminator, comprising: an electrode driving circuit capable of alternately and repeatedly applying, to a discharge electrode, a positive drive voltage and a negative drive voltage as drive voltages so as to output a positive ion and a negative ion from the discharge electrode for corona discharge; a drive controlling device configured to relatively decrease an application time of the positive drive voltage relative to an application time of the negative drive voltage while relatively increasing an amplitude of the positive drive voltage relative to an amplitude of the negative drive voltage so as to relatively increase outputting of the positive ion relative to the negative ion, and to relatively increase the application time of the positive drive voltage relative to the application time of the negative drive voltage while relatively decreasing the amplitude of the positive drive voltage relative to the amplitude of the negative drive voltage so as to relatively increase outputting of the negative ion relative to the positive ion.
