摘要： A fixing device includes a fixing rotator (22), a pressing rotator (27), an oil applicator (30), a first adjuster (34), a surface modifier (41), a second adjuster (42), and a processor (10). The fixing rotator contacts a sheet bearing a toner image. The pressing rotator forms a fixing nip with the fixing rotator. The oil applicator presses at least one of applied members of the fixing rotator and the pressing rotator. The first adjuster adjusts contact/separation of the oil applicator 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 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 lubricant supply device (15) supplies a lubricant to a surface of an image bearer (11) at a position downstream from a cleaning blade (14a) in a rotation direction of the image bearer (11). The lubricant supply device (15) includes a conveying path (15g, 15h) configured to feed the lubricant from an inside of the lubricant supply device (15) to an inside of a cleaning device (14) in which the cleaning blade (14a) configured to contact the image bearer (11) is disposed, without passing through the image bearer configured to bear a toner image. The conveying path (15g, 15h) is configured to feed the lubricant to the surface of the image bearer (11) at a position upstream from the cleaning blade (14a) in the rotation direction of the image bearer (11).
