Fixing device and image forming apparatus

摘要

A fixing device includes a fixing belt, a pressure rotating body, a nip member, a supporting member, a heating source, a heat conducting member and a reflecting member. The pressure rotating body is rotatably arranged outside the fixing belt to come into pressure contact with the fixing belt to form a fixing nip. The nip member is arranged inside the fixing belt to press the fixing belt toward the pressure rotating body. The supporting member supports the nip member. The heating source is arranged inside the fixing belt to emit radiant heat. The heat conducting member is supported by the supporting member in a cantilevered state to come into contact with an inner circumference face of the fixing belt and to absorb the radiant heat. The reflecting member reflects the radiant heat toward the heat conducting member and at least partially comes into contact with the heat conducting member.

主权项

1. A fixing device comprising:
a fixing belt arranged rotatably; a pressure rotating body arranged outside the fixing belt to come into pressure contact with the fixing belt so as to form a fixing nip, and arranged rotatably; a nip member arranged inside the fixing belt to press the fixing belt toward a side of the pressure rotating body; a supporting member supporting the nip member; a heating source arranged inside the fixing belt to emit radiant heat; a heat conducting member supported by the supporting member in a cantilevered state to come into contact with an inner circumference face of the fixing belt and to absorb the radiant heat emitted from the heating source; and a reflecting member configured to reflect the radiant heat emitted from the heating source toward the heat conducting member and to at least partially come into contact with the heat conducting member.
