A belt guide roller (67) includes a roller main body (30), a roller shaft (50) of the roller main body (30), and a shaft attachment section (81). The roller main body (30) makes contact with a cleaning belt (74) for cleaning a draft roller (21, 22) to guide the cleaning belt (74). The shaft attachment section (81) is attached to cover at least a part of an outer surface of the roller shaft (50). The roller main body (30) is provided with a recessed portion (34a, 35a) recessed in an axial direction of the roller shaft (50), and the shaft attachment section (81) is formed to enter the recessed portion (34a, 35a). |
