いた。Conventionally, when replenishing toner to the toner hopper,
Toner is supplied directly to the toner supply port 3 from the toner container 6. Since toner is a fine particle of 10 to 30 microns, even if you replenish it in small quantities quietly, it will float in the toner hopper and leak out from the toner replenishment port 3, contaminating the copying machine body 1. had.

と云った欠点を有していた。For this reason, in recent years, toner cartridges have been used, which are installed in a toner hopper and rotated.
A technique has been proposed in which toner is supplied with an opening provided in a toner cartridge facing downward. However, when the toner cartridge is removed, the toner deposited in the vicinity of the opening falls out, contaminating nearby devices with the toner.

The figure is a sectional view showing the configuration of the toner replenishing device of the present invention. In the figure, 7 is a developing device, which has a developer stirring screw 8 inside and a rotatable sleeve 9 equipped with a magnet inside. The latent image formed on the photoreceptor drum 11 is developed with the developer 10 conveyed by the sleeve 9. A toner hopper 12 is provided above the developing device 7 and supplies toner 13 to the developing device 7 using a replenishing roller 14 disposed in an opening at the bottom. This supply roller 1
Part 4 has a D-cut 9, and its rotation is arbitrarily controlled by detecting the concentration of the developer to cause the toner to fall. Reference numeral 15 denotes a toner supply source such as a fan or a vacuum H2 pump, whose rotation is controlled by a motor 16 . 17 is a first pipe connected to the toner supply source 16, and 18 is a second pipe. The first pipe 17 is removably fitted into the toner supply port of the toner hopper 12 and is disposed inside the toner hopper 12 via a porous ventilation member 19 made of sponge, plastic, etc. A pipe 18 is connected inside the toner container 6.

ースに補給することができる。In the toner replenishing device configured as described above, when the toner supply sources 15 are at the same point, the inside of the pipe becomes negative pressure, so the toner in the toner b container is sucked and flows into the toner hopper 12 through the pipes 18 and 17. sent. Since the toner hopper 12 is provided with the ventilation member 19, only air is allowed to escape to the outside, so that the pressure does not increase and toner leakage can be prevented. And toner hopper 1
When the toner in the toner 2 has settled down, if the ventilation member 19 is lightly hit, the adhered toner will fall, so even if the ventilation member 19 is removed, toner will not scatter. Therefore, when replenishing toner, it is possible to prevent toner from staining equipment or adhering to hands due to toner scattering, and toner can be replenished smoothly.

ー補給をすることができる。FIG. 3 is a sectional view showing another embodiment of the present invention, in which a storage container 20 for temporarily storing the toner supplied to the toner supply port of the toner hopper 12 is removably fitted and arranged. An opening/closing plate 21 is provided on the first tray 6' of the container 20, and the toner is dropped into the toner hopper 12 by opening/closing the opening/closing plate 21 with an external lever (not shown). With this configuration, the same effects as described above can be obtained, and since the toner in the toner hopper 12 has settled down and is normally replenished, toner can be replenished even during copying operation. can do.
