Abstract:
1. An image forming apparatus, comprising: a setting memory that stores multiple voltage settings; two or more voltage applying cleaning members in contact with a voltage applied member at respective contact positions which are closely arranged, the two or more voltage applying cleaning members are simultaneously applied with respective voltages selected from the voltage settings; two or more voltage applying collecting members, each of the two or more voltage applying collecting members is in contact with a respective voltage applying cleaning member; two or more sets of current detectors, each set of current detectors detects a current flowing in a respective contact position based on a current detected for a voltage applied to a corresponding voltage applying cleaning member by a respective first power supply and a current detected for a voltage applied to a corresponding voltage applying collecting member by a respective second power supply; and a setting changer that performs a setting changing process in which a voltage applied to one of the voltage applying cleaning members is changed based on a current detected by one of the two or more sets of current detectors for a contact position of an other of the two or more voltage applying cleaning members and corresponding voltage applying collecting member while a predetermined voltage is applied to the other of the two or more voltage applying cleaning members, wherein the voltage applied member is an image bearing member or a recording medium conveying member.
