Static elimination apparatus and image forming system

A static elimination apparatus comprising:

• a non-contact static elimination unit including an electrode portion for generating ions and configured to eliminate static charge from a sheet on which an image has been formed by an image forming unit, without contacting the sheet;
• and
• a control unit configured to perform, using the non-contact static elimination unit, static elimination processing for eliminating static charge from a plurality of sheets conveyed to the non-contact static elimination unit during execution of a job, and perform, after the static elimination processing, detection processing for detecting whether a maintenance of the electrode portion is necessary after completion of the job,
• wherein, in a case where a cumulative number of sheets as a total number of sheets that have passed through the non-contact static elimination unit since a previous execution of the detection processing is equal to or greater than a first threshold value, the control unit performs the detection processing, and
• wherein, in a case where a number of sheets that have passed through the non-contact static elimination unit in a single job is equal to or greater than a second threshold value smaller than the first threshold value, the control unit performs the detection processing.
