2 is configured as described above, and when not mounted, the regulating means 46 is rotated upward as shown in FIG.
It is stored in a folded state to the side of. Therefore,
The developer cartridge 22 can be formed with a small space used during its transportation and storage. When all the developer contained in the developer container 44 of the developer cartridge 22 attached to the developing housing 12 is consumed and the developer cartridge 22 is to be replaced with a new developer cartridge 22, the fixing means 48 is released or removed to restrict the regulating means 46. The short axis 502, 5
It can be removed from the developing housing 12 by rotating upward about 02 and lifting it together with the developer container 44. After removing the used developer cartridge, the flange portion 443 of the developer container 44 of the new developer cartridge 22 is placed on the flange portion 120 of the developing housing 12, and the seal tape 444 is pulled to open the peeling opening 441. And fixing means 4
The flange portion 443 is fixed to the flange portion 120 of the developing housing 12 by 8. Next, the regulating means 46 is rotated downward about the short shafts 502, 502 to rotate the supporting member 5

When the image generator is mounted and the image generator is operated, the auxiliary roller 38 of the supplying means 18 acts on the roller 26 of the developer applying means 16 in the developer holding area 30, and the peripheral surface of the roller 26 until then. The developer held on the roller 26 is peeled off from the roller 26, and the developer is newly supplied to the peripheral surface of the roller 26. Then, the developer control area 36
In the above, the blade 54 of the regulating means 18 acts on the developer held on the peripheral surface of the roller 26, and the roller 26
The amount of the developer retained on the peripheral surface of the is regulated to a required amount to form a thin layer. Further, by the action of the blade 54, the toner constituting the developer is frictionally charged to have a predetermined polarity, for example, a positive polarity. In the developing area 34, a developer is applied to the electrostatic latent image on the electrostatic photosensitive layer provided on the peripheral surface of the rotary drum 1 to develop the electrostatic latent image into a toner image. When the image generating operation is repeated as described above and all the developer accommodated in the developer container 44 of the developer cartridge 22 is consumed, the new developer cartridge 22 is replaced as described above. As a result, only the developer, which is a consumable item, and the regulation unit that is worn by use and affects maintenance of the image forming performance are replaced. Therefore, the development housing 12, the developer applying unit 16, the supplying unit 18, the stirring unit 20, and the like, which do not affect the maintenance of the image forming performance even after long-term use, can be used without waste.
