PURPOSE:To prevent irregularities in the rotation of a photosensitive body in such a manner that a rotational load is applied to the photosensitive body, without making braking force unstable, and to improve image quality by composing a braking member of an oil damper applying the rotational load to the photosensitive body. CONSTITUTION:Bearings 31 are provided on side plates 30 facing each other, the photosensitive body shafts 14a of the photosensitive body 14 are rotatively supported, and the photosensitive body 14 is provided with a photosensitive body gear 14b on one end, The gear 14b is engaged with a drive transmitting gear 32, and the gear 32 is engaged with the motor gear of a driving motor, to transmit driving force to the gear 14b. Then, the photosensitive body 14 is provided with the oil damper 35 fixed on the same shaft as one photosensitive body shaft 14a of the left in the figure, out of the photosensitive body shafts 14a, and a side plate 30, the rotational load is applied to the photosensitive body 14 by the oil damper 35, and the photosensitive body 14 can be prevented from being rotated with a developing roller. |
