摘要： 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 displaced 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.

摘要： A fixing device includes: a heating rotator and a pressure rotator configured to be pressed against and separated from each other, the rotators being rotated while being pressed against each other to thermally fix a toner image formed on a recording medium at a nip portion between the rotators; and a separating member configured to separate the recording medium to which the toner image is thermally fixed, the separating member being enabled to be brought close to and be separated from the nip portion between the rotators, wherein when the rotators in a pressure contact state are separated from each other, the rotators are separated after the separating member is moved away from the nip portion, and when the rotators in a separated state are pressed against each other, the separating member is brought close to the nip portion after the rotators are pressed against each other.

摘要： A belt-drive device includes a roller, a belt, and a meandering prevention member. The roller is rotatable about an axis. The belt is wound on an outer circumferential surface of the roller. The meandering prevention member is attached to an end of the roller and abuts a side of the belt in the direction of the axis. The meandering prevention member is elastically deformable and has an annular shape. The meandering prevention member has an inner circumferential surface whose diameter is less than an outer diameter of the roller before the meandering prevention member is attached to the roller.
