Abstract

PURPOSE: To prevent a toner bridge from being formed above a discharger and to effect the always stable and satisfactory cleaning operation by providing an agitator in the vicinity of the upper portion of the discharger within a cleaning unit.
CONSTITUTION: Within a cleaning unit 21, there is arranged a cleaning blade 22 in contact with the surface of a photosensitive drum 1, and there is arranged a toner discharging coil spring 24 below a brush 23. The blade 22 is held in a holder unit 25, and the holder unit 25 is arranged rotatably about a shaft 26 so that the leading end of the blade 22 is forced into contact with the surface of the drum 1 by a pressure mechanism only upon the cleaning operation. Thus, a toner bridge is prevented from being formed above the discharger thereby to ensure the discharge of the toner so that the always stable and satisfactory cleaning operation can be performed.
