の収納部を現像器搬入口に合わせるようになっている。(Technical Background) In recent years, various improvements have been made to the handling of color developing devices in image forming apparatuses in order to meet the wide range of color needs. One of the measures is to provide a developer conveyance path in the apparatus main body that connects the developing operation position inside the apparatus main body with the outside of the apparatus main body, so that a predetermined color developer can be easily supplied to the developing operation position from outside the apparatus main body. technology (for example, patent application 1986-16)
3477 etc.) has been proposed. In this technology, when an operator inserts a prepared color developing device into the developing device loading port of the main body of the apparatus, the color developing device is transported along a developing device transport path by a developing device transporting means and fed to a developing operation retreat position. Then, it is positioned at a developing operation position by a positioning mechanism. In addition, we have gone further than this, and have developed a technology that includes a multiple developer storage device (developer autochanger) in the main body of the device, which automatically supplies the selected color developer to the developer inlet. 61
-268388 etc.) have also been proposed. In this technology, when the operator operates a color instruction key provided on the main body of the apparatus, the multiple developer storage device is operated to slide relative to the main body of the apparatus, and the storage section of the selected color developer is moved into the developing device. It is designed to fit into the loading entrance.
収納部が現像器搬入口に合わせられると色現像器は現像
器移送手段によって現像動作退避位置に給送される。When the storage portion is aligned with the developer carrying inlet, the color developer is fed to the developing operation retreat position by the developer transporting means.

昭６１−２７４５８２号等参照）。As in the above measure, when the developing device is transported through a developing device transport path provided in the main body of the apparatus, it is possible to replenish the developing device with developer using a cartridge on the main body side of the device. Since there is no need to provide an insertion section for the developer cartridge in the device itself, the developing device can be made more compact. This is effective in making the developing device transport path and the multiple developing device storage station compact. Therefore, in general, replenishment of developer from a developer cartridge is carried out using a cartridge guide section (which has a cylindrical shape and has a slit-shaped supply port at the bottom of the peripheral wall) provided in the main body of the apparatus (in the developer conveyance path). (See, for example, Japanese Patent Application No. 61-274582).

してしまう虞れもあった。However, when replenishing the developer from the developer cartridge using a cartridge guide provided in the main body of the apparatus, firstly there is a means for aligning the color developer and the developer cartridge filled with the color toner. Because it is not attached, there is a risk of replenishing the wrong color toner to the color developing device that requires developer replenishment.Secondly, since it is always possible to insert a developer cartridge, the developing device may be on replenishment standby. There was also a risk that developer replenishment work would be carried out even though the situation was not correct.

出した状態で完全挿入される。In this case, one guide piece 33b is arranged horizontally regardless of the color of toner to be filled, or the other guide piece 33b
3a is arranged at different positions depending on the color of the toner to be filled. For example, if the cartridge 31 is filled with red toner, its guide piece 33a is matched to the shape of the insertion opening of the cartridge guide member 5 formed when the cartridge 31 is transferred to the red developing device 18 or the developing operation retreat position. That is, the shape setting protrusion 26 of the guide groove 6a shown in FIG.
A can be adjusted to the empty space position after evacuation. Guide pieces 33a of cartridges 31 filled with toners of other colors are also arranged in the same manner. 1. For example, when replenishing developer to the red developing device 18 in the retracted position for developing operation, prepare the developer cartridge 31 filled with red toner, and (side with side) into the insertion opening of the cartridge guide member 59 (at this time, the guide piece 33a engages with the guide groove 6a, the guide piece 33b engages with the guide groove 6b, and the supply port 30 of the developer cartridge 31 (in the vertical upper part) in the sealed state), and then peel off the seal to open the discharge port 32. After that, the developer cartridge 31 is further pushed in. In this case, one guide piece 33a is connected to the guide groove 6a.
The developer cartridge 31 is completely inserted into the cartridge guide member 5 with the handle 34 exposed to the outside of the front side plate 100 by passing through the space where the shape setting protrusion 26a of the insertion port shape setting member 23a has retreated.

。The developer replenishment described in item 1 is performed when the developer is supplied from the color developer or storage device ff1Y to the development operation retreat position in the main body X of the apparatus. This is performed based on a detection signal from a developer detection sensor (not shown) provided inside the developing device. In this way, when replenishing the developer, in the case of the present invention, the cartridge guide member into which the developer cartridge 31 is inserted is used to store the developer without color toner to be filled in the color developing device having the developer replenishment. Cartridge 3
1 is not allowed to be inserted (in developer cartridges 31 containing toners of other colors, the guide piece 33a passes through the developer cartridge 31, making it impossible to insert the developer cartridge 31). Therefore, developer of a different color is not replenished. Further, when the one-color developer is not in the replenishment standby state, the cartridge guide member 5 does not allow the developer cartridge 31 to be inserted (the shape setting protrusions 26a to 26d of the all insertion opening shape setting members 23a to 23d are in the guide groove a). Because the guide piece 33a of the developer cartridge 31 cannot pass through the developer cartridge 31, it becomes impossible to insert the developer cartridge 31. Therefore, unnecessary developer replenishment work is not performed.
