Various types of containers are used to store the ingredients, such as bag-shaped containers and bottle-shaped containers. Then, when replenishing toner, open the lid of the developing device and open the bag [
21 or remove the cap of the bottle to form an opening in the container, and through this opening the toner is transferred to the developing device [
) to replenish the old one. However, toner is a fine powder with a diameter of about 10-odd micrometers, and is easily scattered, and if the container is tilted, it becomes a mist and 19-M particles are deposited in the container. Then, replenish toner to the developing device with the opening of the container facing downward, or open the container. Because the toner is removed from the developing device, the toner may scatter when replenishing toner or when removing the container from the developing device, damaging the operator's hands and clothing, or causing the toner to scatter and cause damage to electronic photographs. There is a risk that they may get inside the recording device and monitor the normal functioning of various parts within the device itself.

る。Therefore, as described in Japanese Utility Model Publication No. 2-8298, a replenishment toner container is provided with a rotating hinge portion that removably engages with a developing device, and the seal of the container is opened to replenish toner. After that, when the container is removed from the developing device, the container must be rotated about the hinge portion so that the opening of the container cannot be removed from the developing device unless the opening of the container is turned in one direction. The toner may scatter when replenishing the toner or removing it from the developing device, staining the operator's hands or clothes, or causing the toner to scatter and stain the operator's clothes.
- Luna - Prevents the electrophotographic recording device from being deposited inside the device and interfering with the normal functioning of various parts within the device body.

It is possible to prevent toner from scattering into the air when toner is replenished. However, it is impossible to completely move the toner that has settled inside the container into the developing device. Therefore, when the container is removed from the developing device after replenishing toner, or when the container is removed from the device for the next toner replenishment, the toner remaining inside the container may stain your fingertips or scatter inside the device. There is a problem in that the normal functioning of various parts within the device body is inhibited.

を通じて現像装置１６に供給される。When replenishing the toner 14 to the developing device 16 using the toner container unit l-1 configured as described below, the I.
The toner container Unisol 1-1 is installed at a predetermined position in the developing device ]-6 so that its supply lower part faces the developing device 16. By pulling the grip part 13 of the sheet film 6 in this state, the folded part 6C of the sheet film 6, which is pressed against the side wall 24 by the first leaf spring 10 and is in a semi-fixed state, is moved to the other end of the first leaf spring 10. 10a and the side wall 24. When the sheet film 6 is further pulled, the folded portion 6c, which has come out from between the other end 10a and the side wall 24, is attached to the other end 1 of the first guide member 3 and the second leaf spring 11.
It comes out from between 1a. As a result, as shown in FIG. 3, the portion of the toner storage section 15 facing the supply lower opens, and the toner 14 inside the toner storage section 15 is supplied to the developing device 16 through the supply lower.

向かって排出される。When the knob 13 is further pulled, the loop portion 6b of the sheet film 6 that forms the toner storage portion 15 is reduced. Therefore, the toner 14 is pushed out toward the developing device 16. As shown in FIG. 1, the side end portion of the sheet film 6 is configured such that the tapered portion 27 gradually becomes narrower toward the supply lower, so that as the loop portion 6b contracts, the loop portion The side edges of 6b are also gradually reduced. Therefore, the toner 14 near the side edge is in a state similar to that of being sealed by the side edge of the sheet film 6 and the tapered portion 27. Therefore, as the loop portion 6b shrinks, the toner 14 near the side end portion is also discharged toward the developing device 16.

As a result, all of the toner 14 contained in the toner storage portion 15 is discharged into the developing device 16. At this time, the loop portion 6b forming the toner storage portion 15 of the sheet film 6 is located on the path from the second guide portion 4 to the third guide portion 5 to the opening 8, as shown in FIG. The slack 6a between the fixing member 9 and the first guide portion 3 shown in FIG.
It is located between the guide member 3 and the second guide portion 4.

At this time, the portion that is in contact with the toner 14 faces the inner surface of the container body 2 and does not come into contact with the operator's hands. Further, the sheet film 6 covering the supply lower is provided with toner 14.
Since this is a part that is not in contact with the toner container unit 1, even if an operator touches this part when removing or disposing of the toner container unit 1, the toner 14 will not adhere to it.
