Fixing device and image forming apparatus

摘要

A fixing device includes a fixing belt, a pressuring rotator, a pressing member, a heat source, a supporting member, and an end cap. The fixing belt is rotatably provided. The pressuring rotator is rotatably provided, and comes into pressure contact with the fixing belt to form a fixing nip between the fixing belt and the pressuring rotator. The pressing member presses the fixing belt from inside toward the pressuring rotator. The heat source is disposed outside of the fixing belt, and heats the fixing belt. The supporting member faces the heat source across the fixing belt, and supports the fixing belt from inside. The end cap is mounted to an end part in the direction of a rotation axis of the fixing belt, and is rotatably supported by the supporting member.
