IMAGE FORMING APPARATUS

An image forming apparatus comprising: an image bearing member, a developing member that forms a toner image with a toner including a metal soap having a polarity opposite to that of the toner, a supply member that supplies the toner to the developing member, and a control unit that executes a metal soap supply operation of supplying the metal soap from the developing member to the image bearing member when an operation other than the image forming operation is executed, wherein the metal soap supply operation includes a first mode and a second mode, and a potential difference between the supply member and the developing member, which causes an electrostatic force in the direction from the supply member to the developing member to act on the metal soap, is smaller in the metal soap supply operation in the second mode than in the first mode.
