An image forming apparatus includes a plurality of photoreceptor drums, a plurality of developing devices, a plurality of polishing members, an endless intermediate transfer component, a primary transfer unit, a secondary transfer unit, a secondary transfer unit, a development refresh unit, and a photoreceptor refresh unit. The photoreceptor refresh unit is configured such that, in executing the photoreceptor-refresh control process, if the development refresh unit detects a toner-deteriorated developing device, the circumferential surface of the deteriorated photoreceptor drum is polished, by the polishing member provided for the deteriorated photoreceptor drum, using the polishing-agent contained in the toner discharged from the toner-deteriorated developing device by the development refresh unit executing the development-refresh control process.
