Then, the rotation driving member 101 drives the rotation force receiving teeth 33 to drive the rotation force transmitting assembly 3 to move a certain distance in a direction away from the container body 1, and since the rotation driving member 101 needs to be retracted, in order to prevent the rotation force receiving teeth 33 from being disengaged from the engagement holes 103 during the retraction of the rotation driving member 101, a torsion spring 32 having a large torsion force needs to be selected.
Finally, the toner container is completely installed, and the rotary driving member 101 drives the toner container to rotate and supplies toner into the image forming apparatus.
The method for taking out the carbon powder container comprises the following steps.
First, the toner container is rotated in the driving direction of the rotation driving member 101, that is, in the direction in which the rotation driving member 101 applies a force to the rotation force receiving teeth 33, that is, in the clockwise direction indicated by the arrow R3 in fig. 7, while the toner container is pulled outward, the second guide surface 335 abuts against the side wall of the engagement hole 103, the rotation force receiving teeth 33 are rotated about the hinge shaft 332 by the reverse pushing force of the second guide surface 335, the engagement portion 331 is rotated in the direction approaching the axis L of the rotation force transmitting head 31, that is, in the direction indicated by the arrow R2 in fig. 9, and the rotation force receiving teeth 33 are rotated to the disengaged position.
Then, the carbon powder container is pulled outwards continuously until the carbon powder container is taken out.
