摘要:
The fixing apparatus is provided with a cleaning pad that is pressed against at least one of roller members composed of a fixing roller, a pressurizing roller and an external heating roller to clean a surface of the roller member, and the cleaning pad is composed of a pad member that cleans the surface of the roller member, and a support member that press the pad member against the surface of the roller member to support. The support member has a plurality of opening portions formed along a thrust direction of the roller member, and has a larger opening area per unit length of the support member at a center part of the support member than that at both edge parts thereof. For example, an interval of holes or slits is narrower at the center part of the support member than that at the both edge parts thereof.
