<P>PROBLEM TO BE SOLVED: To provide a metal belt drive mechanism using a metal belt for presenting high-quality images with highly accurate rotation while preventing electric connection from a driving source to an output part to suppress adversary effects due to electric noises on an imaging part such as a photoreceptor drum, and to provide an image forming device. <P>SOLUTION: The metal belt drive mechanism includes an output shaft 31 for a driving motor 30, a driven pulley 32 provided on a rotating shaft 25 as an input shaft for rotationally driving a driven part (the photoreceptor drum) at a distance from the output shaft 31 as a driving pulley, and the endless metal belt 33 set between the output shaft 31 and the driven pulley 32 in a freely circularly travelling manner. The driven pulley 32 is fixed to the rotating shaft 25 via a bearing formed of an insulating member, or formed of the insulating member to establish an electrically insulating condition between the output shaft 31 and the rotating shaft 25. <P>COPYRIGHT: (C)2011,JPO&INPIT |
