At least 2 of chargers, developing devices, cleaning devices, etc.
A process cartridge is constructed by integrally integrating two process means into a common housing functioning as a support, and this process cartridge is detachably mountable to the main body of the image forming apparatus, thereby improving maintainability and serviceability of the image forming apparatus. There is something.

以下図４を用いて説明する。The housing of the process cartridge has a structure in which a toner container and a cleaning container for storing a developer (toner) and waste toner are integrally formed.
This will be described below with reference to FIG.

ート５１が位置決め支持されている。A photosensitive drum 1 is rotatably supported by the cleaning container 2, and a charging roller 4 that contacts the photosensitive drum 1 and charges the photosensitive drum 1 to a predetermined potential is rotatable and urged against the photosensitive drum 1. The cleaning blade 5 for scraping residual toner on the photosensitive drum 1 and the squeeze sheet 51 for scooping the scraped residual toner are positioned and supported.

持されている。In the toner container 3, a developing sleeve 6 as a developer carrier is rotatably supported, and a developing blade 7 as a thickness regulating member for a toner layer on the developing sleeve 6 is provided.
The toner storage 3a rotatably supports a conveying means 8 for conveying the toner t to the developing chamber 3b.

リーブ６が感光ドラム１へ向って付勢されている。The toner container 3 is rotatably supported by the cleaning container 2 by connecting the end of the support arm 3c to the cleaning container 2 with a pin 3g.
The developing sleeve 6 is urged toward the photosensitive drum 1 by a compression spring 9 contracted between the developing sleeve 6 and the toner container 3.

もれを防ぐシール部材が不要となる。 （３）他の結合方法に比較して結合部品（小ねじ、リベ

The cleaning container lid 10 and the toner container lid 11 are welded by ultrasonic welding for the following three reasons. (1) By being integrally connected to each container by ultrasonic welding, a rigid box-shaped structure is obtained, and rigidity, particularly torsional rigidity, is remarkably improved. (2) A seal member that prevents toner leakage due to welding by ultrasonic welding becomes unnecessary. (3) Compared with other coupling methods, coupling parts (such as small screws and rivets) are unnecessary, and the number of steps required for coupling is small.

う。クリーニング容器２についても同様である。However, in the above conventional example, as shown in the schematic diagram of FIG. 5 showing the toner container 3, the longitudinal wall 3f of the toner container 3 is affected by the energy of ultrasonic welding. It falls down inside the opening 3e, and warpage occurs as shown by the arrow A in the figure. The same applies to the cleaning container 2.

【０００９】そのため、クリーニング容器２に位置決め

らず、不良率も増加してしまう。Therefore, the cleaning blade 5 and the squeeze sheet 5 positioned and supported by the cleaning container 2
The accuracy of the amount of penetration of the leading end into one photosensitive drum 1 deteriorates and the dispersion increases, so that it is necessary to inspect all the positions of the leading ends of the cleaning blade and the squeeze sheet 51, and the defect rate also increases.

【００１０】また、トナー容器３に位置決め支持される
現像ブレード７の現像スリーブ６に対する位置決め精度
が悪化してしまう。Further, the positioning accuracy of the developing blade 7 positioned and supported by the toner container 3 with respect to the developing sleeve 6 is deteriorated.

器３にリブ３ｄを一体に成形し、現像ブレード７の裏側
に突当てている。Further, the mounting surface of the developing blade 7 is set as a positioning reference surface as a contact side surface on the same side as the side of the developing blade 7 which comes into contact with the developing sleeve 6, and is not affected by the tolerance of the thickness of the developing blade 7. Therefore, the developing blade 7 is constantly receiving a force in the peeling direction from the metal holding member 7a. As a countermeasure, a rib 3d is formed integrally with the toner container 3 so that the developing blade 7 does not peel off from the holding member 7a, and is abutted against the back side of the developing blade 7.

【００１２】しかし、前述した様にトナー容器３にトナ
ー容器フタ１１を超音波溶着する際、トナー容器３の壁

との間に隙間が生じてしまう。However, when the toner container lid 11 is ultrasonically welded to the toner container 3 as described above, the ribs 3d and the developing blade 7
And a gap is created between them.

場合、現像ブレード７は保持部材７ａから剥れてしま

題があった。Therefore, when stored for a long period of time or at a high temperature, the developing blade 7 peels off from the holding member 7a, and the contact pressure of the developing blade 7 against the developing sleeve 6 is reduced, and the image density is reduced. However, there is a problem that is reduced.
