Abstract
Toner contains toner base particles and an organosilicon polymer on the surface of the toner base particles. After a toner image is transferred from an intermediate transfer belt to a transfer material, residual toner on the intermediate transfer belt is collected into a belt cleaning device by a blade. A CPU executes supply control of supplying toner from a developing device toward the blade via a photosensitive drum and via the intermediate transfer belt on the basis of a counter accumulated value that correlates with an amount of organosilicon polymer adhering to the blade.
