. Therefore, when opening and closing the lid, vibration occurs when moving to the right.
The toner that is solidified in the toner container unit 1 due to humidity etc. also falls due to vibration.0 After toner has been replenished, move the knob 5 to the left (in the direction of the arrow in Figure 11) to get the state shown in Figure 10. to return to. Since the moving blade 232 is in sliding contact with the sliding surface on the back surface of the upper lid 21, the toner adhering to the sliding surface is removed when the toner falls, and the opening/closing lid always moves smoothly. When the opening/closing lid is moved to the left, the leveling plate 28, which is in a vertical position, rotates in the counterclockwise cutting direction with the center of the shaft 272, as shown by the chain line in Figure 11. Without carrying the toner to the left, it returns so that the tl-1 surface ♀ is cleansed. When the opening/closing lid 23 is closed, the sliding lid 15 is also closed, and the film-like sheet 14 that was peeled off earlier returns to its original state.
