    • A fixing device is provided that suppresses loss in heat radiation from both ends in a longitudinal direction which is a direction corresponding to an axial direction of a fixing roller in a heating member so as to be able to uniform distribution of a temperature in the longitudinal direction of the heating member and to attain uniform fixing capability. A planar heat generating element provided in a heating member includes electrodes at both ends in a circumferential direction so that a flowing direction of current flowing through the planar heat generating element is a direction substantially orthogonal to a longitudinal direction as a direction extending along an axial direction of a fixing roller in the planar heat generating element. The planar heat generating element is constituted so that the both ends in the longitudinal direction thereof have larger thickness than that of a center part thereof.

    • A fixing device includes a fixing belt for fixing an unfixed toner image onto a recording medium, a planar heating member for heating the fixing belt, and a pressure roller. The heating member includes a ceramic heat generating element having a PTC characteristic, and a high-thermal-conductive heat diffusion member. The fixing belt is formed in an endless shape and is supported around, at least, the high-thermal-conductive heat diffusion member, thereby to be heated. The ceramic heat generating element comes into contact with the fixing belt over the full width thereof with the high-thermal-conductive heat diffusion member interposed therebetween. The high-thermal-conductive heat diffusion member comes into contact with the fixing belt over the full width thereof and diffuses heat generated by the heat generating element, in the traveling direction of the fixing belt.

    • A vehicular lighting fixture having an improved appearance, wherein a lamp body and a lens are welded to each other and the inner face of the lamp body is subjected to a surface treatment. The vehicular lighting fixture (1) includes a lamp body (2) having a recess (3) with a front opening, a lens (8) attached to the lamp body (2) in such a manner as to cover the front opening, and a bulb (12) disposed in a lighting fixture space (10) defined by the lamp body (2) and the lens (8). The inner face (13) of the lamp body (2) is subjected to a surface treatment and the lamp body (2) and the lens (8) are connected with each other through their respective welding legs (6 and 9). A groove (7) is formed as a stepped portion inwardly of the welding leg (6) formed on the lamp body (2) to position a masking jig which masks the welding leg of the lamp body from the surface treatment. Also, the width of the legs (6 and 9) are different from each other.
    • 具有改善的外观的车辆照明器具,其中灯体和透镜彼此焊接,并且对灯体的内表面进行表面处理。 车辆照明器具(1)包括具有前开口的凹部(3)的灯体(2),以覆盖前开口的方式安装在灯体(2)上的透镜(8),以及 设置在由灯体(2)和透镜(8)限定的照明器具空间(10)中的灯泡(12)。 对灯体(2)的内表面(13)进行表面处理,灯体(2)和透镜(8)通过它们各自的焊接脚(6和9)彼此连接。 在形成在灯体(2)上的焊接脚部(6)的内侧形成有槽(7),以将掩模夹具定位,从而防止了灯体的焊接腿部的表面处理。 此外,腿部(6和9)的宽度彼此不同。
