Abstract

A charge-eliminating apparatus includes a charge-eliminating member for eliminating charge of a sheet while nipping and conveying the sheet, a voltage applying unit for applying a voltage to the charge-eliminating member, and a detecting unit for detecting a voltage applied to the charge-eliminating member or a current flowing through the charge-eliminating member. A controller measures an electrification charge amount of the sheet based on a detecting result of the detecting unit while the sheet passes through the charge-eliminating member.
