ABSTRACT:
It is a major object of the present invention to break down and level a heap-up of toner built in the hopper through dropping from the cartridge when feeding toner into the hopper and to prevent toner from leakage from the cartridge due to erroneous operation with a remarkably simple and cheap construction. Namely, the leveling member moves a plurality of number of times in line with engaging and disengaging operation of the cartridge for the hopper and opening and closing operation of the cartridge in the same direction of the shutter, thereby causing a heap-up of toner built in the hopper housing of the hopper to be effectively broken down and leveled. Furthermore, only when the shutter is in its closed status for the cartridge, the cartridge can be removed from the opening of the hopper.
