確でかつ操作は簡単であることが必要である。In an electrostatic recording device that uses a dry two-component developer or an electrostatic recording device that uses a -component developer, the developer is consumed as copies are made, and after a large number of copies have been made, It is necessary to replenish the developer. Generally, developer is replenished from a dry developer container that contains developer, and the developer side of the electrostatic recording device is supplied with a hopper.
The kt0 developer is a powder with an average particle size of more than 10 microns and is easily scattered, and when the container is tilted or moved, it becomes a mist and neutralizes and floats in the container. Therefore, the developer container needs to have a structure that prevents floating developer from flying out from the opening, and the opening needs to be able to be easily opened and closed. Furthermore, the developer container must be correctly installed in the popper, and when installing the developer container in the hopper, both the developer container and hopper must be in a closed state, and when toner needs to be replenished, both the developer container and hopper must be in an open state. 2. These operations need to be accurate and easy to operate.

停止する。If the bayonets are simply inserted into each other, both the hopper 1 and the developer container 2 of the electrostatic recording device are in a closed state. However, in this state, the protrusion 235, which is the first operating member, provided on the outer lid of the developer container 2 is engaged with the groove 325, which is provided on the inner lid 32, which is the second movable lid of the hopper 1. Further, the protrusion 315 provided on the opening main body 31 of the hopper 1 is engaged with the blind hole 243 of the middle M2A, which is the first movable lid, through the elongated hole 236 of the outer lid of the developer discharge section 21 as a second operating member. ing. Therefore, when the developer discharge part 21 is rotated counterclockwise in the drawing to engage the bayonet in order to attach the developer container 2, the second movable lid of the hopper 1 is rotated as the developer discharge part 21 is rotated. Rotate the M32 in the middle. On the other hand, the inner lid 24, which is the first movable lid in the developer discharge section 21, is engaged with the protrusion 315, which is the second operating member, provided in the opening main body 31K of the hopper 1, so that the developer can be discharged. Even if the portion 21 is rotated, it does not rotate. Therefore, when the developer discharge section 21 is rotated, the inner lid 32 of the hopper 1 is moved toward the developer discharge section 2.
