    • PROBLEM TO BE SOLVED: To provide a bearing device for developing device and a developing device using the bearing device by which an inexpensive plane bearing can be used and also abnormality does not occur in the rotation of such rotating member as a paddle for supplying developer and an auger for carrying and stirring the developer, which can be stably used for a long time, and whose reliability is high even though the developing device is miniaturized and speeding-up is performed. SOLUTION: The bearing devices 77, 78, and 79 supporting the rotating shafts 57a, 58a, and 59a of a rotating member disposed inside the device housing of the developing device by using the plane bearing 80, and the device is provided with a cap member 81 which is attached inside the device housing of the plane bearing, at least the part of which is exposed inside the device housing, and which is constituted of a material excellent in heat conductivity.
    • 要解决的问题:提供一种用于显影装置的轴承装置和使用该轴承装置的显影装置,通过该轴承装置可以使用便宜的平面轴承,并且在用于供应显影剂的桨叶等旋转构件的旋转中也不会发生异常, 用于承载和搅拌显影剂的螺旋推运器,其可以长期稳定地使用,并且即使显影装置被小型化和加速进行,其可靠性高。 解决方案:通过使用平面轴承80,支撑设置在显影装置的装置壳体内部的旋转构件的旋转轴57a,58a和59a的轴承装置77,78和79,并且该装置设置有盖构件 81,其安装在平面轴承的装置壳体内部,至少其一部分暴露在装置壳体内部,并且由导热性优异的材料构成。
