After the sealing cap 6 seals the developer inlet port 26, the sealing cap 6 is not easily disengaged from the container body 2 during transportation and use, and for this reason, the developer supply container 1 further includes an anti-disengagement structure for preventing disengagement of the sealing cap 6, as shown in fig. 2A and 2B, the container body 2 is provided with a barb 27, the sealing cap 6 includes a handle portion 61 and a catching portion 62 which are engaged with each other, and the catching portion 62 is engaged with the barb 27 to prevent the sealing cap 6 from being rotated in a direction opposite to the direction indicated by j to disengage from the container body 2.
Specifically, the barb 27 includes a guiding surface 271 and a clamping surface 272 which are adjacently arranged, the clamping portion 62 includes a guided surface 621 and a clamped surface 622 which are adjacently arranged, when the sealing cover 6 rotates in the direction indicated by j and the clamping portion 62 contacts with the barb 27, the guided surface 621 is guided by the guiding surface 271, the clamped surface 622 is opposite to the clamping surface 272 after the guided surface 621 passes the highest point of the guided surface 271, preferably, the guiding surface 271 and the guided surface 621 are both inclined surfaces relative to the rotation axis L, the clamping surface 272 and the clamped surface 622 are both straight surfaces, that is, the guiding surface 271 and the guided surface 621 are both inclined relative to the rotation axis L, and the clamping surface 272 and the clamped surface 622 are both parallel to the rotation axis L, therefore, even if an external force opposite to the rotation direction j is applied to the handle portion 61 of the sealing cover 6, when the clamping surface 272 and the clamped surface 622 are opposite, the rotation movement of the sealing cover 6 is prevented, and the sealing cover 6 is separated from the container body 2.
As described above, in the developer supply container 1 according to the present invention, the pump portion is not provided, but the movable body 513 which moves with the rotation of the rotary body 511 is provided to the rotary body 511, and the moving direction of the movable body 513 intersects with the rotation axis of the rotary body 511, and the developer is pushed toward the developer discharge port 4225 by the reciprocating motion of the movable body 513, so that the discharged developer is not sucked back, and sufficient supply of the developer is ensured.
