The upper opening 2 is for dropping and releasing toner (not shown), and when not in use, paper or the like (not shown) is pasted thereon to prevent the toner from spilling. A stopper 3a, which is a handle for rotating the 3-piece cartridge 1 and protrudes from the cylindrical body part, is connected to a cartridge guide 5, which will be described later.
The cartridge 1 is set in a predetermined position by coming into contact with the edge of the cartridge. In addition, an insertion guide protrusion 4 is provided on the leading end edge of the insertion side of the toner cartridge 1 in the same direction as the stopper 33, which positions the cartridge 1 when it is inserted, and also directs the cartridge opening 2 toward the top when the cartridge 1 is inserted. That's what I do.

置決めをなすようにしである。On the other hand, the cartridge storage section 7 into which the toner cartridge 1 is inserted is made of a cylindrical body that is slightly larger than the cartridge 1, and has an opening 9 that is larger than the cartridge and the opening section 2 on the lower side. Furthermore, a door-shaped cartridge guide 5 is integrally protruded from the cartridge insertion side of the storage section 7, and one end surface 5a of the guide 5 is formed to assist in guiding the insertion position when the cartridge is inserted, and the other end surface 5a is formed to assist in guiding the insertion position when the cartridge is inserted. 5b is designed to stop the rotation of the stopper 3a and determine the position of the toner drop.

ッジガイド5の端面5aの延長部分には上記挿入用ガイ
ド4と嵌合するガイド溝8を突設している。A guide groove 8, which fits into the insertion guide 4, is provided in a protruding manner approximately right next to the side surface of the cartridge storage portion 7, that is, in an extension of the end surface 5a of the cartridge guide 5.
また、カートリッジガイド5の内底面には第2図ないし

ガイド溝8の外に出ている。To insert the toner cartridge 1 into the toner supply device configured as described above, first peel off the sealing material covering the opening 2 of the cartridge 1, grasp the handle 3 or the cartridge body, and insert the cartridge guide 5. Place it on top. Then, the cartridge 1 is pushed toward the storage section 7, and the insertion guide protrusion 4 and the guide groove 8 are fitted together, and then the cartridge 1 is pushed in until the stopper 3a comes into contact with the edge of the storage section 7. In this case, the insertion guide protrusion 4 protrudes outside the guide groove 8.

ッパー10内に落下する。Thereafter, the handle 3 is rotated until the stopper 3a abuts the other edge 5b of the cartridge guide 5. In this case, the guide protrusion 4
This prevents the cartridge 1 from being removed. As the cartridge 1 rotates, the stored toner falls into the hopper 10 from the opening 2 of the cartridge 1 through the opening 9 of the storage section 7.

く。The image forming apparatus is used in such a state and detects when the amount of toner in the hopper 10 has become less than a predetermined value, notifies the user and replaces the cartridge with the next one. For the exchange of 1,
Turn the handle 3 and pull out the cartridge 1 with the stopper 3a in contact with the edge 5a of the cartridge guide 5.

ホッパー10内に落下する。When pulling out the cartridge 1, the toner adhering to the outside of the cartridge 1 or the inside of the confinement part 7, that is, the toner that is attached to the opening 2 by rotating the cartridge 1 when supplying toner.
The toner spills out before the toner turns straight down, and the toner that adheres to the inner wall of the storage section also adheres to the outer wall of the cartridge L. The adhered toner falls off due to friction caused by the ejecting action of the cartridge 1, and the toner falls onto the cartridge guide 5. The toner that has fallen onto the cartridge guide 5 is gradually collected in the toner collection groove 6 by photographing the entire image forming apparatus when the image forming apparatus is in use, and moves along the slope in the groove 6, and the toner is moved to the opening 9. It falls into the hopper 10 through the.

ことができる。In this way, the toner that previously fell into the device and contaminated the inside of the device is caught in advance by the guide part, and the toner collected during use is captured in the collection groove, and the vibration of the device is used to collect the toner. Since the toner is collected from the collection groove into the hopper, there is no contamination within the device, and the toner can be used effectively.
