2. Description of the Related Art In an image forming apparatus using toner for development, for example, in a color image forming apparatus, a plurality of developing apparatuses each containing four color toners of yellow, magenta, cyan and black are used. ing. Therefore, each of the four color developing devices is provided with a dedicated toner replenishing device, and when the amount of toner remaining in the toner storage portion of the toner replenishing device decreases or the image density becomes low,
A toner replenishing device, which has been detected by the detection means and has a reduced amount of toner, is replenished with toner of a predetermined color from a corresponding toner cartridge.

Generally, when replenishing the toner from the toner cartridge to the toner replenishing device, the toner supply port of the toner containing portion and the toner replenishing port of the toner cartridge are connected in a sealed state so that the toner does not scatter to the outside. However, the means of replenishment has come to be used. At that time, the toner in the toner cartridge was supplied to the toner containing portion by hitting the outside of the toner cartridge. As the toner is supplied, the toner flows into the toner accommodating portion, but unless the amount of air corresponding to the toner replenishment amount does not flow out, the air pressure in the toner accommodating portion rises, so that the toner replenishment becomes difficult. Further, since the toner is replenished in the sealed state as described above, a part of the air in the toner storage portion enters the toner cartridge, but is blocked by the replenishing and dropping toner, and the smooth outflow of air also occurs. It is difficult and the toner cannot be replenished smoothly. In order to improve such a defect, an improved technique as disclosed in JP-A-4-473 is disclosed. That is, when the toner is replenished from the outside to the toner containing portion that supplies the toner to the developing device, an air outlet (ventilation hole) for discharging only the air corresponding to the replenishment amount of the toner from the inside of the toner replenishing portion is provided. Is solved by.

[0004]

As described above, in the conventional device, the vent hole provided in the toner storage portion is provided in the developing device when dust and metallic foreign matters fall into the toner replenishing device through the vent hole. By mixing the dust and the metallic foreign matter into the developer on the developing sleeve, unevenness of the layer thickness of the developer occurs in the rotating direction of the developing sleeve. Therefore, a light white streak (a phenomenon in which the developer is not formed at a predetermined image density) occurs in the recorded image. In the recent developing method in which a DC bias and an AC voltage are superimposedly applied to the developing sleeve, the toner vibrates within the narrow developing interval due to a narrow developing interval between the photosensitive drum and the developing sleeve and a high alternating electric field. I am letting you. Under such developing conditions, when a conductive foreign substance passes through the narrow developing interval, latent image destruction occurs in a ring shape around the developing sleeve, resulting in a large image defect. Further, there is a concern that a bias potential may drop due to an overcurrent from the developing sleeve, or a malfunction of the apparatus may occur.

Further, a toner cartridge is mounted on the toner replenishing device a maximum of 200 times within the life guarantee period of the device, and the toner flows out from the vent hole.
Therefore, the toner that has flowed out from the ventilation holes stains the inside of the device,
The toner accumulates. The accumulated toner stains the hands of the user of the apparatus, or accumulates and diffuses in various parts inside the machine, causing image stains. In order to prevent the above-mentioned toner stains, it is possible to install a filter inside the ventilation hole, but clogging with the toner and exhaust response at the time of toner replenishment deteriorate, and the original image forming function The decrease and deterioration of the value became a problem.

The present invention was particularly conceived to remedy the above drawbacks. That is, in order to replenish the toner to the toner replenishing device, by mounting the toner cartridge, the air in the toner replenishing device is discharged from a part of the toner cartridge, or the toner replenishing device completes the toner replenishment preparation. The purpose is to smoothly replenish the toner by opening the air outlet in conjunction with the operation.

FIG. 1 is a sectional view showing the structure of a color image forming apparatus using the toner replenishing device of the present invention. An outline of the configuration and a series of operations will be described based on the drawings.

The photosensitive drum 10 as an image bearing member having an OPC photosensitive layer coated on the surface is in one direction (clockwise direction in the figure).
After being driven to rotate, the static eliminator 11 performs static elimination to remove the charge from the previous printing, and the charger 12 uniformly charges the peripheral surface to prepare for a new print. After this uniform charging, the image exposure means 13 performs image exposure based on the image signal. The image exposing means 13 is rotated and scanned by a rotating polygon mirror 131 with laser light emitted from a laser light source described later, and an optical path is bent by a reflecting mirror 133 through an fθ lens 132 and the like, and the photosensitive drum 10 previously charged is charged. A latent image is formed on the surface of the photosensitive drum 10 by being projected onto the peripheral surface of the.

Around the periphery of the photoconductor drum 10, there is a developer composed of a mixture of toner such as yellow (Y), magenta (M), cyan (C), black (K) and a magnetic carrier. Filled developing devices 14A, 14B, 14
C and 14D are provided, and first, the development of the first color is performed by the developing sleeve 141 which has a built-in magnet and rotates while holding the developer. The developer is regulated to a predetermined thickness on the developing sleeve 141 by the layer forming rod and is conveyed to the developing area. An AC bias voltage VAC and a DC bias voltage VDC are superimposed and applied between the photoconductor drum 10 and the developing sleeve 141. Here, the potential of the exposed portion of the photosensitive drum 10 is VL, the surface potential of the charged photosensitive layer other than the exposed portion is VH, and the DC bias voltage VDC is |
By setting such that VH |> | VDC |> | VL | is established, the toner given the opportunity to be separated from the carrier by the AC bias voltage VAC does not adhere to the portion of VH higher in potential than VDC, It adheres to the exposed portion of potential VL, which is lower than VDC, and is visualized and developed.

After the development of the first color is completed in this way, the second color (eg, magenta) image forming process is started.
The photosensitive drum 10 is uniformly charged again, and a latent image based on the image data of the second color is formed by the image exposure means 13. For the third color (cyan) and the fourth color (black), the same image forming process as for the second color is performed, and a total of four colors are developed on the photosensitive drum 10.

To replenish the yellow (Y), magenta (M), cyan (C), and black (K) toners, four toner replenishing devices 40 are provided, and the developing device 14A has a toner replenishing pipe 44. The toner replenishing pipe 45 for the developing device 14B, the toner replenishing pipe 46 for the developing device 14C, and the toner replenishing pipe 47 for the developing device 14D are replenished from the toner replenishing device 40, respectively. Reference numeral 50 shown in FIG. 2 is a toner cartridge that supplies toner to the four toner supply devices 40 for yellow (Y), magenta (M), cyan (C), and black (K). On the other hand, the recording paper P, which is the transfer material fed by the paper feed mechanism 22 by the paper feed cassette 21, is formed between the photosensitive drum 10 and the transfer belt 31 by the transfer belt device 30 in which the transfer belt 31 is stretched. The multicolor image on the peripheral surface of the photosensitive drum 10 is collectively transferred to the recording paper P by being fed to the nip portion (transfer area) 35. Here, a high voltage is applied to the shaft 32a of the upstream holding roller 32 of the transfer belt 31, and the shaft 32a
The conductive brush 34, which is installed at a position opposed to the transfer belt 31 with the transfer belt 31 interposed therebetween, is grounded, and the fed recording paper P enters between the brush 34 and the transfer belt 31, and the brush 34
Due to the electric charges injected into the recording paper P, the recording paper P is attracted to the transfer belt 31 and enters the transfer area. The recording paper P separated from the photoconductor drum 10 is separated from the transfer belt 31 while being neutralized by using the shaft 33b of the holding roller 33 on the downstream side which stretches the transfer belt 31 as a counter electrode. The toner attached to the transfer belt 31 is removed by the cleaning blade 37. Note that the transfer belt 31 has a shaft 33 of the holding roller 33 on the downstream side during the formation of the multicolor image.
It is separated from the photosensitive drum 10 with b as the center of rotation.

Recording paper P separated from the transfer belt device 30
Has a heating heater 232 inside at least one heating fixing roller 231, and is conveyed to a fixing device 23 composed of a pair of pressure-bonding rollers 233, and the heating fixing roller 231 and the pressure-bonding roller. By applying heat and pressure between 233, the toner adhering to the recording paper P is melted, fixed on the recording paper P, and then carried out of the apparatus.

After the transfer, the toner remaining on the peripheral surface of the photosensitive drum 10 is discharged by the static eliminator 15 to reach the cleaning device 16 and the cleaning blade 16a contacting the photosensitive drum 10 causes the toner inside the cleaning device 16 to be removed. It is scraped off by the scraper, carried out by a screw, etc. and stored in the collection box. The photoconductor drum 10 from which the residual toner has been removed by the cleaning device 16 is neutralized by the static eliminator 11 and then uniformly charged by the charger 12 to enter the next image forming cycle. If the recording paper P is not separated from the transfer belt 31 and winds around the photoconductor drum 10 and enters above the static eliminator 15, the cleaning blade 16a and the electrode wire may be damaged. A jam sensor 36 for detecting wrapping is attached near the static eliminator 15.
