摘要： A fixing device includes an endless belt rotatable in a predetermined direction of rotation and a nip formation assembly disposed opposite an inner circumferential surface of the endless belt. An opposed rotary body is pressed against the nip formation assembly via the endless belt to form a fixing nip between the endless belt and the opposed rotary body through which a recording medium bearing a toner image is conveyed. A belt holder contacts and supports each lateral end of the endless belt in an axial direction thereof. The belt holder is isolated from the opposed rotary body with a first interval interposed therebetween in the axial direction of the endless belt.

摘要： A fixing device includes an endless flexible belt, an elongated stationary pad, a rotary pressure member, a low-friction sheet of lubricant-impregnated material, a first adhesive layer, and a second adhesive layer. The endless flexible belt is looped into a generally cylindrical configuration extending in an axial direction thereof for rotation in a rotational, circumferential direction thereof. The elongated stationary pad is stationarily disposed inside the loop of the belt. The rotary pressure member is disposed parallel to the belt. The rotary pressure member presses against the stationary pad via the belt to form a nip therebetween. The low-friction sheet of lubricant-impregnated material covers the stationary pad to supply lubricant between the stationary pad and the belt across the nip. The first adhesive layer is disposed between the low-friction sheet and the stationary pad. The second adhesive layer is disposed between the low-friction sheet and the stationary pad.

摘要： A separator includes a front edge disposed opposite an outer circumferential surface of an endless belt. The front edge contacts and separates a recording medium from the endless belt. A separation plate mounts the front edge. A contact plate projects from the separation plate in an axial direction of the endless belt and contacts a belt holder that supports the endless belt. A bracket projects from the separation plate in a direction orthogonal to the direction in which the contact plate projects from the separation plate. The bracket includes a notch that engages the belt holder. The contact plate contacting the belt holder and the notch of the bracket engaging the belt holder produce an interval between the front edge of the separator and the outer circumferential surface of the endless belt.
