PURPOSE:To reduce cost by decreasing the work load of a service man. CONSTITUTION:A driving roller 1 is fitted to one end of a photoreceptor frame 13, a driven roller 2 is fitted to the other end, and a V-shaped photoreceptor arm 30 is attached to a central part. Further, a rib 31 is provided between the central part and the other end thereof. Moreover, a tension roller 3 is provided in the first arm part 30a of the photoreceptor arm 30, and a second arm part 30b is made opposite to the rib 31. A photoreceptor 4 is supported by rollers 1, 2 and 3. At the time of shipping, a tension releasing part 32 is inserted between the rib 31 and the second arm part 30b, so that tension affecting the photoreceptor 4 is released. At this time, a projection 32c is engaged with a detecting sensor installed in a device main body. Further, when the part 32 is pulled out, the tension is applied to the photoreceptor 4, and simultaneously the detecting sensor generates a signal for driving an equipment. |
