An image forming apparatus for forming a toner image on a transfer material using an intermediary transfer member includes an image bearing member; a toner image forming member for forming a toner image on the image bearing member; an intermediary transfer member in contact with the image bearing member; a first bias applying member for forming a first transfer bias between the image bearing member and the intermediary transfer member to effect primary transfer of the toner image; a second bias applying member for forming a second transfer bias between the intermediary transfer member and transferring member to effect secondary transfer of the toner image; third bias applying member for applying a voltage to an electrode for charging residual toner remaining on the intermediary transfer member to transfer the residual toner back onto the image bearing member, after the transfer; wherein the first, second and third bias applying members are capable of applying bias voltages of opposite polarities; whereby the apparatus is operable in: a first cleaning mode wherein the residual toner is transferred back onto the image bearing member simultaneously with the primary transfer; a second cleaning mode electrostatically shifting the toner deposited on the transferring member onto the intermediary transfer member; a third cleaning mode where the toner deposited on the electrode is electrostatically shifted onto the intermediary transfer member.
