<p>A fixing device (18) includes a fixing belt (21), a pressuring member (22), a pressing member (25), a guiding member (27), a cap member (28), an elastic member (29, 61) and a detecting mechanism (30). The pressing member (25) includes a pressing face (46) pressing the fixing belt (21) to a side of the pressuring member (22). The fixing belt (21) includes a bulging part (21c) arranged at the downstream side from a fixing nip (32) in a conveying direction. The cap member (28) includes a facing part (48a) facing to the bulging part (21c). Before the pressuring member (22) comes into pressure contact with the fixing belt (21), a gap (G) is arranged between the bulging part (21c) and facing part (48a). When the pressuring member (22) comes into pressure contact with the fixing belt (21), the bulging part (21c) bulges toward an external diameter side of the fixing belt (21) to fill up the gap (G) and the cap member (28) is held by an end part (21a, 21b) of the fixing belt (21) via the elastic member (29, 61).</p> |
