<P>PROBLEM TO BE SOLVED: To provide a photoreceptor driving gear which improves driving transmission accuracy and makes a good image obtainable with a simple configuration. <P>SOLUTION: The photoreceptor driving gear, such as a copying machine or a printer, is coaxially and separately provided, on an output shaft 2 of a photoreceptor driving motor 1, with: a photoreceptor driving transmission means 3 which drives a photoreceptor; and a photoreceptor peripheral part driving transmission means 4 which drives a photoreceptor peripheral part. The driving transmission using a photoreceptor timing belt 7 is employed for the photoreceptor driving transmission means 3, and the driving transmission using a gear train from the driving motor output shaft is employed for the driving transmission means for the photoreceptor peripheral part. In addition, an idle gear supporting member 15 for supporting an idle gear 9 located downstream the driving transmission means 4 of the photoreceptor peripheral part is disposed, is made a separate body from the driving motor supporting member 13 and is fixed in a way as not to come into contact with the driving motor supporting member 15. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
