Abstract

PURPOSE:To cause toner to easily move along an inclined inner surface by rotating a container and to excellently discharge all of the toner by forming so that the diameter of a barrel part provided with a spiral projection is made smaller from a toner outlet toward an opposite side. CONSTITUTION:By rotating the set toner container 24 by means of a motor 22, the toner 42 is fed to an attaching part 24A by the spiral projection 25 on the inner surface and discharged from the toner outlet 26, and supplied to a developing device 11 through a toner discharge tube 36 and a toner replenishing pipe 19 to be used for development. The toner is apt to stay in the bottom of the container 24 when remaining toner becomes a little, but it is fed along a grade toward the outlet 26 because the barrel part 24B is tapered, and it is effectively utilized. Since the residual is caused when the grade is too small and the capacity of the toner container gets small when it is too large, the grade is ordinarily set at 0.2-5 degrees.

されたものが知られている。2. Description of the Related Art Conventionally, as shown in FIG. 7, a toner supply device for supplying toner to a developing section in a developing device includes a case 1, a motor 2 with a speed reducer, and a toner container connected to the motor 2. The toner container 4 is provided with a holder 3 and a toner container 4 which is removably attached to the toner container holder 3 and has a spiral protrusion 6 on the inner surface. The toner outlet 4A is moved to the toner outlet 4A formed near one end.
There is known a structure in which the liquid flows out from the tank and is sent to a developing section (not shown).

が複雑となる等の問題点を生じる。The reason for the toner remaining is considered to be that the toner container 4 is arranged horizontally, and therefore the inner surface 4B of the bottom thereof is also horizontal. Therefore, in order to prevent this toner from remaining, the toner container 4 may be mounted at an angle so that the mounting side to the toner container holder 3 is lowered. However, when the toner container is arranged at an angle, the overall height becomes thicker and extra space is required. In addition, in order to provide the toner container at an angle, the toner container holder 3, motor 2, etc. must also be provided at an angle, resulting in problems such as a complicated structure.

is formed. Further, as shown in FIG. 4, a positioning projection 2 and a fixing projection 28 are formed on the outer peripheral surface of the toner container 24. As shown in FIG. On the other hand, the toner container holder 23 has a toner outlet 3o formed at a position corresponding to the outlet 26 of the toner container, a positioning groove 31 formed at a position to receive the positioning protrusion 27, and a fixing protrusion. A fixing claw 32 is provided at a position where the receiver 28 is inserted. Thus, the mounting portion 24A of the toner container 24
By inserting the tip into the toner container holder 23 and pushing the positioning groove 31 and the positioning protrusion 27 together, the fixing protrusion 28 on the outer surface of the toner container 24 is pushed between the fixing claws 32 of the toner container holder 23. Restrained in that position, the toner container 24 is fixed to the toner container holder 23. At this time, the toner outlet 26 of the toner container 24 is connected to the toner outlet 3 on the toner container holder 23 side.
Matches 0. Also, to remove the toner container 24,
Simply pull the toner container 24 firmly. As a result, the fixing protrusion 28 and the fixing claw 32 are disengaged, so that the toner container 24 can be removed. Note that a packing 33 such as a sponge is provided around the toner outlet 30 to prevent toner from leaking to the outside.

As shown in factor a, when the toner discharge pipe 36 is not inserted into the toner supply pipe 19, the shutter 39 is pressed against the disc 41 at the tip by the spring 40, closing the discharge port 36A. This shutter 39 has a flange on the outer periphery. 39A
However, the flange 39A is connected to the toner discharge pipe 3.
The toner replenishing pipe 19 is formed at a distance d away from the tip of the toner replenishing pipe 19 by a distance d, which is larger in thickness. With this configuration, when the toner discharge pipe 36 is inserted into the opening formed in the toner supply pipe 19, as shown in FIG. The toner discharge pipe 36 comes into contact with the outer surface of the supply pipe 19 and is prevented from moving, and then the toner discharge pipe 36 is further pushed in, and the discharge port 36A on the lower surface is opened.

でよい。Next, a method of using the toner container 24 having the above structure will be explained. Toner container 24 is filled with toner 42 (see FIG. 3) and supplied with toner outlet 26 sealed with a suitable sealing material. To set this toner container 24 in the toner supply device 12, the toner container holder 23 is
The toner outlet 3o is placed at the top,
All that is required is to unseal the toner outlet 26 of the toner container 24 and insert the tip attachment portion 24A into the toner container holder 23.

出口２６から排出される。Next, when the set toner container 24 is rotated by the motor 22, the toner 42 is sent toward the attachment portion 24A by the spiral protrusion 25 on the inner surface of the toner container 24, and is discharged from the toner outlet 26.

排出されたトナーはトナー排出管３６．トナー補給パイ
プ１９を介して現像装置１１に供給され、現像に使用さ
れる。The discharged toner is sent to the toner discharge pipe 36. The toner is supplied to the developing device 11 via the toner supply pipe 19 and used for development.

防止できる。When the toner 42 in the toner container 24 runs out, the toner, which is not easily conveyed by the spiral protrusion 26, tends to accumulate at the bottom of the toner container 24. however,
In the toner container 24 of this embodiment, the body portion 24B is tapered, so that the inner surface 24b of the bottom thereof slopes downward toward the attachment portion 24A having the toner outlet. Due to this gradient, the toner 42 is sent toward the attachment portion 24A, is reliably discharged from the toner outlet 26, and is effectively utilized. In this way, residual toner in the toner container can be prevented.

に設定される。Here, if the slope formed on the inner surface of the bottom of the toner container (angle α in Fig. 3) is too small, the toner will not be conveyed effectively and will remain, and conversely, if it is too large, the toner will be discharged well. However, the volume of the toner container becomes small, which is not preferable. Taking these into consideration, the angle is usually set at 0.2 to 6 degrees.

きるという効果を有するものである。Effects of the Invention As is clear from the above description, in the toner container of the present invention, the diameter of the body portion provided with the spiral protrusion of the toner container becomes smaller as it goes from the mounting portion side having the toner outlet to the opposite side. Therefore, by placing this toner container horizontally and rotating it, the toner inside can be moved toward the toner outlet side by the spiral protrusion, and the amount of residual toner can be reduced. Even if the conveying action by the spiral protrusion is reduced, the inner surface of the body at the bottom of the container is sloped downwards toward the toner outlet, so that the toner can be reliably moved toward the toner outlet. This has the effect that all toner can be used effectively.
