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 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.

摘要： A fixing device includes a support supporting a nip formation assembly that presses against an opposed rotary body via an endless belt to form a fixing nip between the endless belt and the opposed rotary body. The support includes a base contacting the nip formation assembly. An upstream projection projects from the base in a pressurization direction of the opposed rotary body at a position on the base corresponding to or upstream from an upstream edge of the fixing nip in a recording medium conveyance direction. A downstream projection projects from the base in the pressurization direction of the opposed rotary body at a position on the base corresponding to or downstream from a downstream edge of the fixing nip in the recording medium conveyance direction. The downstream projection is spaced apart from the upstream projection in the recording medium conveyance direction.

摘要： A fixing device includes a fixing rotator heated by a heater and a pressing rotator pressed against the fixing rotator to form a fixing nip therebetween, through which a recording medium bearing a toner image is conveyed. A heat shield interposed between the heater and the fixing rotator is movable in a circumferential direction of the fixing rotator to shield the fixing rotator from the heater in a variable axial shield span of the fixing rotator. The fixing rotator performs fixing rotation to convey the recording medium through the fixing nip while heating the recording medium and supplemental rotation other than fixing rotation. The heat shield moves to a decreased shield span position where the heat shield shields the fixing rotator from the heater in a decreased axial shield span of the fixing rotator during supplemental rotation thereof.
