B is glued. The film is made of a resin film such as polyester, and requires an appropriate elastic restoring force. This is because the film 3 LI B u is lined with the elastic member (material) A and the support rod 3 in the fixed position is
1 and 32, and is stretched in an L shape at 5 so as to surround a part of the outer circumference of the photosensitive drum 3. At this time, the elastic member 30A is stretched with elastic force so as not to easily contact the photosensitive drum 3. Need to back up. In addition, even if the flexible film 30B comes into contact with the outer peripheral surface of the developing port 5A of the developing device 5 when it is loaded into the copying machine main body, it will not affect the developing roll 5. A flexible and smooth coating material that does not damage the outer peripheral surface is selected.

る。Next, the operation procedure for the image forming unit equipped with the protection device B will be explained. Before the image forming unit A is installed in the copying machine main body, that is, during storage and transportation, the protective device B is connected and fixed as shown in Figure 3, and the outer peripheral surface of the photosensitive drum 3 is protected by a protective sheet 30. This prevents your hands and equipment from getting dirty or getting damaged by touching them.

がない。The integrated image forming unit A and the protection device B are inserted into the insertion section of the main body of the copying machine. Prior to this insertion, the developing device 5 rotates the developing roll 5A around the swing shaft 5E.
is automatically or manually retracted by about 3 to 611 g away from the installed position of the photosensitive drum 3 by, for example, a two-part operation of a copying machine, so that the developing drum surface does not come into contact with the developing drum.
ユニッ）Ａは複写機本体の所定位置へ装填完了したとき
、ロック手段（不図示）によって位置決め固定される。When the unit A is completely loaded into a predetermined position in the main body of the copying machine, it is positioned and fixed by a locking means (not shown).

奏する。As mentioned above, this BAVi is connected by a reef protection device that covers the koji release part of the photosensitive tram in the image forming unit with a protection sheet, and this protection device is attached to the copying machine body together with the above unit from C. Since only the protective device is removed in step 5, the unit will not be protected even when the unit is stored outside the copying machine, when it is installed inside the main body, and even if objects are hit directly against the photosensitive drum. The sheet prevents scratches, and even if you touch it with your hands, it won't get dirty due to fingerprints. Therefore, since the unit is easy to handle, the handling work can be carried out efficiently and easily, which is a practical advantage.
