An image forming apparatus includes an image carrier that holds a toner image, a rotary developing device including a plurality of developing units to develop an electrostatic latent image on the image carrier with toner by supplying the toner from the developing unit opposing the image carrier, a foreign-substance receiving plate that receives a falling foreign substance, a transfer unit that transfers the toner image from the image carrier onto a recording medium, and a fixing unit that fixes the transferred toner image on the recording medium. Each of the developing units includes a developer container that stores developer containing magnetic carriers and toner, and a developing roller that supplies the toner in the developer for development of the electrostatic latent image. The rotary developing device further supports a foreign-substance collecting member that magnetically collects a magnetic foreign substance on the foreign-substance receiving plate.
