Abstract
A fixing apparatus includes: an endless fixing belt; a pad member having a receiving surface and a supported surface; a pressing rotator pressing the fixing belt against the receiving surface and forming a nip portion between an outer circumferential surface of the fixing belt and the pressing rotator; a supporting member supporting the pad member; and a heating source to heat the fixing belt. The supporting member includes a base abutting on the supported surface of the pad member, and an erected wall erected from the base to partition a space inside the fixing belt into an upstream space and a downstream space. The erected wall is disposed upstream or downstream in a recording-material transport direction, from an intermediate position of the nip portion. The heating source is disposed in a larger one of the upstream space and the downstream space.
