Abstract

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.
