<P>PROBLEM TO BE SOLVED: To provide a drive transmission device demountable with easy operation while reducing vibration in transmitting rotation driving force from a driving source for a driving side member to a demountable driven side member, and to provide an image forming device using the same. <P>SOLUTION: The drive transmission device comprises the driving side member 21 connected to the driving source, the driven side member 20 to which driving force is transmitted from the driving side member 21, a rotational center shaft 22 to be rotatable relatively to the driving side member 21 and the driven side member 20, and an elastic member 23 arranged between the driving side member 21 and the driven side member 20. The elastic member 23 is cylindrically formed to be radially deformed with the movement of the driven side member 20 toward the driving side member 21 so that the driving force can be transmitted between the driving side member 21 and the driven side member 20. <P>COPYRIGHT: (C)2009,JPO&INPIT |
