Abstract
A charge-eliminating apparatus includes a charge-eliminating member configured to come into contact with a sheet and eliminate static charges from the sheet, a power supply configured to apply a voltage to the charge-eliminating member, a current detection circuit configured to detect a current flowing through the charge-eliminating member, and a control unit configured to control a value of the voltage by the power supply, based on a detection result obtained by the current detection circuit when the sheet passes over the charge-eliminating member, such that the current falls within a predetermined range with respect to a target value, wherein the control unit acquires a detection result of an environment detection sensor that detects an environmental condition, and wherein the control unit changes the target value based on the detection result of the environment detection sensor during execution of a job that eliminates static charges.
