FIXING DEVICE AND IMAGE FORMING APPARATUS

摘要

A fixing device includes a fixing belt, a pressuring member, a nip forming member, a supporting member, a heating source, a heat conducting member, and a reflecting member. The pressuring member comes into pressure contact with the fixing belt to form a fixing nip. The nip forming member presses the fixing belt toward the pressuring member. The heat conducting member comes into contact with an inner circumference face of the fixing belt and absorbs a radiant heat emitted from the heating source. The reflecting member includes a reflecting part and a regulating part. The reflecting part reflects the radiant heat emitted to the supporting member toward the heat conducting member. The regulating part is unified with the reflecting part and comes into contact with the inner circumference face of the fixing belt to regulate looseness of the fixing belt.

主权项

1. A fixing device comprising:
a fixing belt arranged rotatably; a pressuring member arranged outside the fixing belt to come into pressure contact with the fixing belt so as to form a fixing nip; a nip forming member arranged inside the fixing belt to press the fixing belt to a side of the pressuring member; a supporting member supporting the nip forming member; a heating source arranged inside the fixing belt to emit radiant heat; a heat conducting member coming into contact with an inner circumference face of the fixing belt and absorbing the radiant heat emitted from the heating source; and a reflecting member including
a reflecting part reflecting the radiant heat emitted to the supporting member from the heating source toward the heat conducting member, anda regulating part unified with the reflecting part and coming into contact with the inner circumference face of the fixing belt to regulate looseness of the fixing belt.
