Abstract:
A surface roughness Rz of an outer peripheral surface of an intermediate transfer belt is 0.05 μm or more, and toner contains toner base particles and an organosilicon polymer on the surface of the toner base particles. After residual toner on the intermediate transfer belt is collected by a blade into a belt cleaning device, the blade has a coating layer on its surface facing the intermediate transfer belt, the coating layer containing the organosilicon polymer.
