    摘要: A heating apparatus which can increase the temperature of a heating element to a target temperature in a short time and ensures temperature uniformity of the heating element. In the heating apparatus, when the specific resistance of a material of a heat generating layer of a heating roller is ρ (μ′Ωcm), the average thickness of the heat generating layer is 5ρ (μm) or more but not more than 15ρ (μm), and the thickness error is 1.2ρ (μm) or less. For instance, when the heat generating layer is copper having a specific resistance of 1.7 (μ′Ωcm), the average thickness of the heat generating layer is 8-25 (μm), and the thickness error is 2 (μm) or less. Thus, the heating roller having a short heat increasing time and excellent temperature uniformity is provided.

    摘要: In a fixing apparatus using an induction heating type of heating apparatus, there are provided an excitation apparatus that generates magnetic flux, an opposed core located opposite the excitation apparatus, a fixing belt that is induction-heated by the aforementioned magnetic flux, and magnetism masking elements that block magnetic paths corresponding to paper non-passage areas of fixing belt between the excitation apparatus and the opposed core. By blocking magnetic paths between the excitation apparatus and the opposed core by the magnetism masking elements, magnetic flux that induction-heats the fixing belt is effectively masked, and an excessive rise in temperature of paper non-passage areas of fixing belt is prevented.

    摘要: As a cooling mechanism that cools the entire paper passage area of a heat-producing belt, a rotational drive method of the heat-producing belt is employed and the heat-producing belt is cooled by rotational cooling by being made to idle when paper is not being passed through. An excitation apparatus and the above-described cooling mechanism are controlled so that recording paper is not passed through and the heat-producing belt is cooled while being heated over the heating width when the small-size recording paper is passed through until the temperature detected by a paper non-passage area temperature detecting sensor is at or below a predetermined fixing temperature. This fixing apparatus enables an excessive rise in temperature of a paper non-passage area of the heat-producing belt to be efficiently eliminated, and the temperature distribution of heat-producing belt to be made uniform in a short time.

    摘要: A fixing apparatus can prevent an excessive rise in temperature of a paper non-passage area due to diverted flow of magnetic flux from a paper passage area of a heat-producing element to a paper non-passage area thereof has a small configuration, A center core is rotated by a rotation section, bringing cutaway parts to a magnetic path masking position, and the degree of magnetic coupling between the center core and a heat-producing roller is weakened, suppressing an excessive rise in temperature of paper non-passage areas of the heat-producing roller. With this fixing apparatus, switching of the intensity of magnetic coupling between the center core and heat-producing roller can be performed simply by rotating the center core. Also, with this fixing apparatus, it is not necessary for magnetism suppressing elements to be provided as separate members, enabling the configuration to be made simpler and less expensive.

    摘要: An optical pickup device includes a light source, a movable condensing lens, a rising prism or a rising mirror, an objective lens, and a phase plate. The light source emits laser light, and the movable condensing lens converts the laser light into converging light or diverging light. The rising prism or the rising mirror converts an optical axis of laser light passing through the condensing lens into a substantially vertical direction. The objective lens condenses the laser light, of which the optical axis is converted by the rising prism or the rising mirror, to an optical disk. The phase plate is provided between the condensing lens and the objective lens, and includes stepped portions that are formed at portions facing each other and have different thicknesses. The phase plate corrects astigmatism, which is generated by the rising prism or the rising mirror, by making a part of laser light having a size larger than a predetermined size pass through the stepped portions of the phase plate.According to the above-mentioned structure, it may be possible to correct the astigmatism of not only laser light directed to the optical disk but also light reflected from the optical disk of which the polarization direction is different by about 90° from that of the laser light directed to the optical disk, without requiring power or a specific system when astigmatism generated by the rising prism, the rising mirror, or the like is corrected.
