Abstract
A cleaner is provided. The cleaner includes at least two cleaning brush members to electrostatically remove residual toner on an object; a memory; a voltage applicator to apply a voltage to the cleaning brush members based on the setup voltage values stored in the memory; a current detector to detect the amounts of currents flowing through contact portions of the object with the cleaning brush members; and a setup voltage changing device to change the setup voltage values based on the amounts of currents detected by the current detector. The setup voltage changing device performs change of the setup voltage values for the cleaning brush members at a time.
