Abstract
A cleaning device includes a cleaning blade disposed in contact with a rotator, a toner collecting section disposed along the rotator and the cleaning blade and includes a groove extending in an axial direction of the rotator, a conveyor disposed in the groove, and an agitator disposed on a side of a rim of the groove. The conveyor rotates to convey the toner in a longitudinal direction of the groove. The agitator vibrates through contact with the conveyor and includes comb-tooth portions lined in a comb shape in the longitudinal direction of the groove, and bent portions, each of which is bent from an end of one of the comb-tooth portions. The comb-tooth portions contact a circumference of the conveyor to vibrate. The bent portions are lined at intervals smaller than intervals on a base side of the comb-tooth portions.
