PROBLEM TO BE SOLVED: To provide an inexpensive reliable driving device capable of transmitting uniform rotation to a photoreceptor by regulating the free vibration of a flywheel. SOLUTION: A holding bearing 124 supporting one end side of a flywheel shaft 94 is attached to a main body casing 58. The bearing 124 is provided with a bearing part 126 and a regulating part 128. The bearing part 126 supports the outer peripheral surface on one end side of the shaft 94, and the regulating part 128 comes in contact with the end face of the shaft 94 and regulates movement in a shaft direction. A spring plate 130 attached to the casing 58 overhangs from the regulating part 128. A hole part is formed on the plate 130, whereby flexibility is given to the bearing 124. Therefore, needless stress is not generated on the bearing 124 by unbalanced load caused by supporting the shaft 94 at three points. |
