PURPOSE:To suppress the dispersion of developer at the time of loading/ unloading of a developer feeding means and at the time of opening/closing its door by bringing into contact a part of an opening/closing mechanism of the door with a part of a body in the closing process of the door and applying reverse force against the energizing force to the opening/closing mechanism. CONSTITUTION:A slide shutter 201 for opening/closing an aperture part 204 of a toner cartridge is energized in the closing direction by springs 208, 208 to open a right cover. At that time, the energizing force of the springs 208, 208 is applied to the slide shutter 201 to close the aperture part 204. At the time of closing the right cover, the reverse force against the energizing force of the springs 208, 208 is applied to the slide shutter 201 to open the aperture part 204. Since the aperture part 204 of the toner cartridge is surely closed at the time of loading/unloading of the toner cartridge or at the time of opening/closing the right cover on the way of processing, the inside of the machine body can be prevented from contamination due to the dispersion of toner. |
