摘要： A separation device separates a recording medium ejected from a fixing nip formed between a first rotator and a second rotator from the first rotator. The separation device includes a separator including a front end disposed opposite the fixing nip and the recording medium and a plurality of recesses disposed on the front end of the separator at least in a conveyance span on the separator where the recording medium is conveyed. The plurality of recesses includes a first recess extending in a first extension line that is oblique relative to a recording medium conveyance direction and a second recess adjacent to the first recess and extending in a second extension line that is oblique relative to the recording medium conveyance direction. The second extension line overlaps the first extension line in a direction perpendicular to the recording medium conveyance direction to define an overlap span.

摘要： A separation device includes an endless belt, a rotary body, a separation supporter, and a transfer mechanism. The separation supporter presses against an inner circumferential surface of the endless belt downstream from an area of contact between the endless belt and the rotary body in a recording medium conveyance direction to curve the endless belt toward an outer circumferential surface side of the endless belt at a greater curvature than a curvature of the endless belt at the area of contact between the endless belt and the rotary body. The transfer mechanism switches the separation supporter between a first position and a second position farther from the area of contact between the endless belt and the rotary body than the first position.

摘要： An image forming apparatus includes a fixing belt stretched across a first roller and a second roller including an elastic layer. A pressure rotator presses against the second roller via the fixing belt to form a fixing nip between the pressure rotator and the fixing belt. A recording medium bearing a toner image is conveyed through the fixing nip. A clearance detector detects a clearance between the first roller and the second roller. A mover moves the pressure rotator with respect to the second roller in a pressing direction in which the pressure rotator presses against the second roller via the fixing belt and a separation direction in which the pressure rotator separates from the second roller. A controller controls an amount of movement of the pressure rotator moved by the mover toward the second roller based on the clearance detected by the clearance detector.

摘要： A fixing device includes a fixing rotator, a pressing rotator, an oil applicator, a first adjuster, a surface modifier, a second adjuster, and a processor. The fixing rotator contacts a recording medium bearing a toner image. The pressing rotator forms a fixing nip with the fixing rotator. The oil applicator is pressed against at least one of applied members of the fixing rotator and pressing rotator. The first adjuster adjusts contact/separation of the oil applicator with respect to the applied member. The surface modifier contacts the fixing rotator to modify a surface thereof. The second adjuster adjusts contact/separation of the surface modifier with respect to the fixing rotator. The processor allows the surface modifier to modify the fixing rotator surface after the oil applicator contacts the applied member, and the oil applicator to separate from the applied member after the surface modifier is separated from the fixing rotator.

摘要： An image forming apparatus includes a rotary fixing member cleaner that includes a freely rotatable rotary unwinding member, around which a cleaning web winds, a rotary winding member to wind the cleaning web thereon from one end thereof, and a load applicator to apply a load to the cleaning web unwound from the rotary unwinding member. The rotary fixing member cleaner removes any unnecessary substance adhering to an outer circumferential surface of the rotary fixing member therefrom by unwinding and moving the cleaning web from the rotary unwinding member in an opposite direction to a direction of movement of the outer circumferential surface of the rotary fixing member at a contacting point at which the cleaning web contacts the outer circumferential surface of the rotary fixing member. The load applicator presses against the cleaning web winding around the rotary unwinding member at a prescribed angular contact position.
