Abstract

PURPOSE: To prevent the removed developer from dropping and scattering around, by providing a guide material which receives the residual developer, which does not pass through the drop preventing material position, to guide it to the direction apart from the surface of the image carrier, in the upper stream side of the drop preventing material.
CONSTITUTION: The redidual toner on drum surface 111 is slided and removed by cleaning blade 12. Most of the removed toner is received by end part 131 of sheet 13 and drops along sheet 13 up to feed screw 15. Meanwhile, the toner which is not received and enters the reverse face of sheet 13 is held till it becomes a mass of a certain quantity by electrostatic adhesion. Though this toner starts dropping when it becomes such large mass that its own weight cannot be supported by electrostatic force, the dropping toner drops to feed screw 15 through toner path 18 provided under sheet support part 16 and is sent to the storage equipment. Thus, the removed developer can be prevented from dropping and scattering around.
