Abstract:
1. An image forming apparatus comprising: an image bearing member, which bears a toner image; a toner image forming unit, which forms a toner image onto the image bearing member; a transfer unit, which electrostatically transfers the toner image on the image bearing member to a recording material; a first cleaning member to which a voltage is applied to remove residual toner on the image bearing member after the toner image is transferred; a second cleaning member to which a voltage is applied to remove toner from an area of the image bearing member from which the toner has been removed by the first cleaning member; detecting means for detecting an electric current when a predetermined voltage is applied to the second cleaning member or a voltage when a predetermined electric current is applied to the second cleaning member, the predetermined voltage or the predetermined electric current being applied to the second cleaning member when the area of the image bearing member that has been contacted with the first cleaning member to which the voltage is applied is in contact with the second cleaning member; and voltage changing means for changing the voltage applied to the second cleaning member to remove the toner, based on a detection result of the detecting means.
