摘要： A developing device includes a rotator that rotates around a shaft, and a bearing element that supports the shaft to a housing. A sliding element formed of a composite material that contains self-lubricating thermoplastic olefin resin as a base material is used as the bearing element. The sliding element formed of the composite material has at least a ratio of numerical values of “Rockwell hardness”/“bending elastic modulus” in a range from 25 to 45, and provides a sliding surface of which a frictional coefficient is lower than that of the sliding element formed of the base material.

摘要： A developing device which can stably supply a developer to a latent image carrier by preventing the scattered developer from being discharged and thereby preventing the developer from being discharged despite that the amount of developer within the developing device does not increase, and an image forming apparatus using the developing device. A block member serving as a scattered developer discharge prevention member is provided so as to block a path through which the developer scattered as a result of a conveyance operation of a supply screw serving as a developer conveying member moves toward a developer discharge port. Accordingly, the scattered developer is prevented from reaching the developer discharge port and being discharged therefrom.
摘要翻译：一种显影装置，其能够通过防止散射的显影剂的排出而稳定地将显影剂供应到潜像载体，从而防止显影剂排出，尽管显影装置内的显影剂的量不增加;以及图像形成装置，其使用显影装置。设置用作散开的显影剂排出部件的块部件，以阻挡作为用作显影剂传送部件的供给螺杆的输送操作而散发的显影剂朝向显影剂排出口移动的路径。因此，防止散开的显影剂到达显影剂排出口并从中排出。

摘要： A development apparatus comprises three developer conveyance paths with separate functions for the supply, recovery and agitation of a developer, in which a reduction in size of the apparatus can be achieved. An image forming apparatus comprises the development apparatus. By provision in a development region width α of a supply opening for delivering developer from the downstream end in the direction of conveyance of an agitation conveyance path to the upstream end in the direction of conveyance of a supply conveyance path and a surplus opening for delivering developer from the downstream end in the direction of conveyance of the supply conveyance path to the upstream end in the direction of conveyance of the agitation conveyance path, a space saving of the upper part of the development apparatus can be achieved and a space saving of the development apparatus as a whole can be achieved compared with a conventional development apparatus.
