    • PROBLEM TO BE SOLVED: To provide a developer container constituting a developing device of an image forming apparatus, the developer container being capable of improving the conveying ability and the durability of a developer conveying member for conveying developer.SOLUTION: A rotation base member 13B of an agitator body (developer conveying member) 13 is rotated with a rotation axis 13A inside a container body 12, and when an agitator body (developer conveying member body) 13C made of elastic pieces is rotated with the rotation axis 13A as a center, developer (toner) accommodated into the container body 12 is agitated and conveyed by the rotation of the end portion of the agitator body 13C with the inner peripheral wall of the container body 12 elastically contacted thereto. At this time, since the agitator body 13C is biased to the downstream side from the upper stream side of the rotation direction by a biasing member 13D, an elastic return force is increased with the conveying ability of the developer improved. Thus, the reduction of the elastic return force is prevented and the durability is also improved.
    • 要解决的问题:为了提供构成图像形成装置的显影装置的显影剂容器,显影剂容器能够改善用于输送显影剂的显影剂输送构件的输送能力和耐久性。解决方案: 搅拌器体(显影剂输送部件)13在容器主体12内旋转轴线13A旋转,当以旋转轴13A为中心旋转由弹性片制成的搅拌体(显影剂输送部件体)13C时,显影剂 容纳在容器主体12内的墨粉(调色剂)通过搅拌器主体13C的端部的旋转与容器主体12的内周壁弹性接触而被搅拌和输送。 此时,由于搅拌器主体13C被偏置构件13D从旋转方向的上游侧偏压到下游侧,所以随着显影剂的输送能力的提高,弹性回复力增加。 因此,防止弹性回复力的降低,并且耐久性也提高。
