Abstract
Toner contains toner base particles and an organosilicon polymer on the surface of the toner base particles, and silica particles are added to the toner as an external additive. The surface roughness Rz of an intermediate transfer belt, against which a blade abuts, in the width direction of the intermediate transfer belt perpendicular to the belt conveying direction is larger than the average particle diameter Ry of the organosilicon polymer and is smaller than the average particle diameter Rk of the silica particles.
