PROBLEM TO BE SOLVED: To properly set an applied voltage to each voltage application member so that a value of flowing current is a target current value in a structure in which two voltage application members to which a voltage is simultaneously applied are brought into contact with a position where the voltage application members are close to each other on a voltage applied member.SOLUTION: In a state where a predetermined voltage is applied to a second cleaning brush roller 106, a setting value changing process is performed by applying a voltage for changing setting to a first cleaning brush roller 102, detecting the current amount (IB1+IC1) flowing the contact position between the first cleaning brush roller and an intermediate transfer belt 8 by current amount detecting means, and changing a set voltage value applied to the first cleaning brush roller based on the detected current amount. |
