Summary:The invention provides an imaging device with a belt component for ensuring a long life of running stability. A location limit roller (74) and a driven roller (34) move along axial direction thereof with the help of an annular groove (76) under the condition that location of a projected wall (78) is deviated in width direction of a conveying belt (36), thus the stress on the projected wall (78) acting on the conveying belt (36) is within a preset value. Therefore, the conveying belt (36) may not move corresponding to the location deviation and snaking thereof is reduced showed by the solid line when location of the projected wall (78) of the conveying belt (36) has a big deviation. Moreover, problems such as rupture etc. of the projected wall (78) are reduced because the stress more than necessary is not acted on the projected wall (78). The invention is able to prolong service life of the conveying belt (36), comparing to the imaging device (10) not using this.
