A power storage apparatus, a fixing apparatus, and an image formation apparatus

摘要

A power storage apparatus (41) is disclosed, which includes a charge-able and discharge-able capacitor unit (42), discharged power being supplied to an electrical load (23). The power storage apparatus includes a detection unit (48-50) configured to determine whether an amount of power stored by the capacitor unit (42) falls less than a predetermined magnitude at a predetermined voltage. Degradation of the power storage apparatus (41) is determined based on a detection result of the detection unit (48-50), and a setting value concerning charging and discharging is adjusted.
