An image forming apparatus includes an image bearing member; a plurality of first developing devices for developing an electrostatic latent image formed on the image bearing member at a developing position using a developer which includes a toner and a carrier; a rotatable member rotatable in a path including the first developing position, for supporting the plurality of first developing devices, wherein each of the plurality of first developing devices is effective to discharge excess developer produced by receiving the developer including the toner and the carrier to outside of each of the plurality of first developer devices using a rotation of the rotatable member; and a second developer container for developing an electrostatic latent image formed on the image bearing member at a second developing position using a developer including a toner, wherein the second developing device is disposed at a position so as to be non-rotatably adjacent to the image bearing member.
