A vibration insulating member fitting method includes the steps of: positioning
and wrapping a sheet-like vibration insulating member 2 around a shaft 3
having an air suction/exhaust portion 5; holding the sheet-like vibration
insulating member 2 onto the shaft 3 by air suction; and inserting
the shaft 3 that sucks the sheet-like vibration insulating member 2 by
the air suction into a hollow cylinder 13 of a photosensitive drum 1
to stop the air suction, causing the sheet-like vibration insulating member
2 to be tightly fitted onto the inner wall surface of the photosensitive
drum 1 by a restoring force of the sheet-like vibration insulating member
2. A vibration insulating member recovering method includes the steps of:
inserting a shaft 3 having an air suction portion into a sheet-like vibration
insulating member 2 fitted on an inner wall surface of a hollow cylinder
13 of a photosensitive drum 1; starting air suction to suck and hold
the sheet-like vibration insulating member 2 onto the shaft 3; detaching
the sheet-like vibration insulating member 2 from the inner wall surface
of the hollow cylinder 13 of the photosensitive drum 1; and taking
the shaft 3 out of the hollow cylinder 13 of the photosensitive drum
1, with the sheet-like vibration insulating member 2 being sucked
and held on the shaft 3.
