An image fusing apparatus includes a heating belt including a resistance heating layer, an insulating layer formed on an inner surface of the resistance heating layer, and a release layer formed on an outer surface of the resistance heating layer; a heating supporting roller disposed (positioned) inside the heating belt and rotating with the heating belt; a pressing roller disposed (positioned) parallel to the heating supporting roller and in contact with the outer surface of the heating belt to form a nip; and an electricity supplying member to supply electricity to the resistance heating layer of the heating belt. A thickness of paper non-contact areas of opposite side end portions of the resistance heating layer of the heating belt is the same as or thicker than the thickness of a paper contact area of a middle portion of the resistance heating layer thereof.

A near field optical recording/reproducing apparatus includes a light source, an objective lens to form a spot by focusing light emitted from the light source, a solid immersion lens to generate an evanescent wave by using the spot formed by the objective lens, a photodetector to measure an amplitude of a gap error signal that is totally reflected by the solid immersion lens, and an operating unit to generate a normalized gap error signal by using an amplitude of a driving signal applied to the light source and the amplitude of the gap error signal measured by the photodetector.
