PURPOSE:To easily and inexpensively suppress the vibration of a photosensitive drum by providing a vibration absorbing device coaxially with the photosensitive body. CONSTITUTION:The vibration absorbing device 10 is fixed coaxially with a revolving shaft 5 to the left side of the revolving shaft 5. This vibration absorbing device 10 consists of an inner peripheral side sleeve 11, a vibrationproofing member 12 consisting of hard rubber, and a rigid ring 13 fixed to the outer periphery of this vibrationproofing member 12. The vibrationproofing member 12 consisting of the hard rubber is vulcanized and adhered between the sleeve 11 and the rigid ring 13, by which these members are integrally formed. The vibrations above the prescribed level of the photosensitive drum 3 are absorbed by the vibration absorbing device 10 in this way. The vibrations of the photosensitive drum 3 are thus effectively suppressed. |
