列部に表示する。A conventional developing device includes a developing roll facing the photoreceptor P ram and an agitating member for agitating the developer in the device. When toner runs out, a toner cartridge is installed and toner is replenished as needed. A remaining toner detection device is installed near the bottom of the developing device, and when it detects that the amount of toner has decreased to the bottom of the developing device, it displays this on the copying machine row.

搬的〒あった。The remaining toner detection device in the developing device of a conventional copying machine detects the remaining toner inside the developing device using a vibrating element or a light 1aI detector, and this is displayed on the outside of the copying machine for use. It was a good idea to notify the operator of XJI when replenishing toner.

に検知できないというトラブルも生じてくる′。However, the components of such conventional detection devices are expensive and complicated, and productivity is not good.Furthermore, the mounting position of the IW on the developing device is limited to near the bottom of the developing device. There is a problem in that the location of the device is also subject to restrictions. In addition, if toner adheres to the surface of a sensor such as a vibrating element or photoelectric element, the sensitivity of the sensor changes and the detection level of the remaining amount of toner changes. This may also cause problems such as not being able to be detected.

A rotating display unit that is linked to the agitation member through the device indicates that the toner is insufficient for the first part. The rotation display unit is linked to the stirring member, but
The speed is significantly reduced by the speed reduction device compared to the stirring member, and the amount of toner is displayed within a range of one rotation or less.
このようにトナー残ｉＩ検知手段をトナーカートリッジ

ることによりトナー４の残量を表示する。The toner cartridge 5 has an opening in the axial direction, and this opening is closed with a seal before use, but when in use, the seal is peeled off and the cartridge is inserted into the developing device in the axial direction. The toner cartridge 5 is provided with a substantially U-shaped stirring member 6 that rotates close to the inner circumferential surface thereof, and a gear 9 connected to the stirring member 6 is provided at one end of the toner cartridge 5. The rotation is transmitted to the stirring member 6 by meshing with the gear of the developing roll drive system. Further, the other end of the toner cartridge 5 is provided with a toner remaining amount display member 8 connected to the stirring member 6 via a decelerator 7. The remaining amount of toner 4 is displayed by rotating the toner.

ち攪拌部材６０回転数によって決定される。When displaying the remaining amount of toner within the range in which the display member 8 rotates quickly, the speed reducer 7 reduces the rotation speed of the display member 80 to one part of the rotation speed of the stirring member 60 (in the case of one rotation for one copy). . Further, when displaying the remaining amount of toner within the range of one revolution of the display member 8, the rotation speed of the display member 8 is as follows. Decelerate to 00. In this manner, the reduction ratio is determined by the rotation angle of the display member 8 to display the remaining amount of toner, the capacity of the toner cartridge 5, and the number of possible copies due to stiffness, that is, the number of rotations of the stirring member 60.

とも可能である。As shown in the front view of the display member 8 in FIG.
is divided into two colors, for example, red (fA line area) and green (plain area), and by rotating the display member 8 in the direction of arrow A, the proportion of each color in the display window 10 of the copying machine can be determined. The amount of toner remaining is displayed. In this embodiment, if green (plain area) occupies a large proportion of the display window 10, it indicates that there is a large amount of toner remaining, and if red (shaded area) occupies the entire area within the display window 10, toner is insufficient. It represents something.l
- The display of the toner 'lAf is not limited to the two kinds of colors as shown above; for example, characters indicating the remaining amount of toner, numbers indicating the amount of remaining toner, etc. may be displayed depending on the rotation of the display member 8. Therefore, the agitating member 6 may be configured to appear within the display window 10.Also, the agitating member 6 is rotated by a gear 9 connected to the outside of the toner cartridge 5 meshing with a gear of the developing roll drive system, but it may be rotated by another independent drive. It is also possible to rotate it depending on the system.

、カートリツ・）５の容量に応じたトナー残葉検知が正
確に行なえる。As described above, since the toner cartridge 5 is equipped with the agitating member 6 and the toner remaining amount display member 8 integrated through the decelerator 7, the remaining amount of toner can be accurately displayed according to the rotational speed of the agitating member 6. I can do it. By recognizing the display member 8 through the display window 10 of the paste copying machine, it is possible to easily predict when the toner cartridge 5 will be replaced, and preparations for replacement can be made in full. Furthermore, the decelerator 7 and display member 8 are replaced together with the toner cartridge 5!
, the remaining toner can be accurately detected according to the capacity of the cartridge.

易に判断できる。According to the present invention, a removable toner cartridge is provided with a toner remaining indicator F (i material, and this indicator member is a cartridge
The stirring member that rotates in the cage is linked via a speed reducer.
, when the toner is used a predetermined number of times, the toner shortage is displayed. Furthermore, since the remaining amount of toner can be accurately displayed, the user can easily determine when it is time to replace the toner cartridge.
また、トナーカートリッジに表示部材を備えたことによ
