Abstract
A charge-eliminating apparatus configured to perform charge elimination on a sheet includes a charge-eliminating member configured to perform charge elimination on the sheet, a power source configured to apply a voltage to the charge-eliminating member, a contacting member configured to be brought into contact with the sheet, a detection circuit configured to detect a voltage applied to the contacting member or a current flowing in the contacting member, and a controlling unit configured to control the power source, wherein the controlling unit determines a value of the voltage applied from the power source to the charge-eliminating member during charge elimination by the charge-eliminating member based on a detection result from the detection circuit during passage of the sheet along the contacting member, and wherein the voltage applied to the contacting member undergoes constant current control, and the voltage applied to the charge-eliminating member undergoes constant voltage control.
