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： A fixing device includes an endless belt, a drive rotator, a driven rotator, a rotation detector, and circuitry. The drive rotator contacts and rotates the endless belt. The driven rotator contacts an inner circumferential surface of the endless belt. The rotation detector detects a rotational speed of the driven rotator. The circuitry is operatively connected to the rotation detector to control a rotational speed of the drive rotator based on the rotational speed of the driven rotator detected by the rotational detector. The circuitry changes the rotational speed of the drive rotator when a recording medium bearing a toner image is not conveyed over the endless belt.

摘要： A fixing device includes a first rotator rotatable in a given direction of rotation and a second rotator contacting the first rotator to form a fixing nip therebetween through which a recording medium bearing a toner image is conveyed. A heater is disposed opposite and heats at least one of the first rotator and the second rotator. An abutment separably contacts the first rotator to refresh an outer circumferential surface of the first rotator. A mover is connected to the abutment to move the abutment with respect to the first rotator. A degradation estimator is operatively connected to the mover to estimate a degradation level of the outer circumferential surface of the first rotator and control the mover to move the abutment with respect to the first rotator according to the degradation level of the first rotator.

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： 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.
