困難である。 A typical prior art technique will be described with reference to FIG. In this prior art, a pair of support members 4 having an arc-shaped support portion 3 open to the magnetic brush developing device 2 side are fixed at a fixed position on the machine body. The photosensitive drum 5 is rotatably supported by fitting a bearing 7 that receives the rotating shaft 6 into the support portion 3 . Furthermore, the main body 8 of the developing device 2 is provided with a pressing protrusion 9 for pressing the bearing 7 against the support member 3, and by fixing the main body 8 on the support member 4, the bearing 7 can be fixed. Supported by here,
The distance between the outer circumferential surface of the photosensitive drum 5 and the outer circumferential surface of a developing roller (not shown) in the developing device 2 must be kept uniform along the axis of the photosensitive drum 5. However, in this prior art, the pressing projections 9 are integrally formed on both side walls of the main body 8. Therefore, the copying machine has become larger and the photosensitive drum 5 of the main body 8 has become larger.
If the length along the axis of the photosensitive drum 5 becomes large, there is a possibility that the distance cannot be maintained uniformly along the axis of the photosensitive drum 5 due to distortion of the main body 8 or the like. Moreover, it is difficult to adjust the distance.
