<P>PROBLEM TO BE SOLVED: To provide a photoreceptor driving device by which an excellent image can be obtained by solving the conventional problem with a simpler constitution. <P>SOLUTION: This photoreceptor driving device is provided with an idler pulley 11 in order to impart initial tension to a photoreceptor driving timing belt 7 coupling a timing pulley 2 and a photoreceptor drum pulley 6. The pulley 11 is turnably attached to a supporting shaft 13 on a supporting member 12. The member 12 is fixed in a housing or the like through a binding member 15 and an elastic member 16 at the part of a sliding hole 14 on the member 12. In fixing the member 12, the appropriate initial tension is given to the belt 7 by a pressuring member 17, and then the member 12 is fixed. <P>COPYRIGHT: (C)2003,JPO |
