クしている限り、上記回動上昇は阻止される。By the way, as shown in FIGS. 1, 10 and 11, the developer replenishment container 3 is provided with a protrusion 34. This protrusion 34 is inserted into the notch of the receiving container 1 during the step of placing the replenishment container 3 on the receiving container 1, pressing it from above, and locking the protruding portion 33 with the lock 7 (FIG. 11(a)). The elastic member (plate spring) 8 provided at the location 102 is pushed downward to elastically deform it as shown in FIG. 11(b). Therefore, when the replenishment container 3 is set at the replenishment position for receiving developer and replenishing the developer into the container 1, the elastic member 8 pushes the container protrusion 3b inserted into the recess 14. It serves as a rotational fulcrum and receives an elastic biasing force in the direction of rotation and upward movement from the replenishment position. However, as long as the locking member 7 engages the protrusion 33 and locks the replenishment container 3, the above rotational upward movement is prevented.
