显影装置以及图像形成装置
摘要：
本发明提供即使显影辊与循环系统螺杆的速度关系发生变化，也不会使显影剂滞留于回收螺杆的显影剂存积部且循环系统螺杆的显影剂存积部的显影剂液面也不会变动的显影装置以及图像形成装置。显影装置具有：显影辊(131、136)，其承载显影剂，并且被旋转驱动；循环系统螺杆(151、156)，其被旋转驱动，从而搅拌显影剂并且将其输送到显影辊(131、136)；以及回收螺杆(146)，其被旋转驱动，从而使在静电潜像的显影后自显影辊(136)剥离出的显影剂返回到循环系统螺杆(151、156)而进行回收，能够分别独立地控制循环系统螺杆(151、156)的驱动速度以及回收螺杆(146)的驱动速度。
摘要（英）：

The inventoin provides a developing apparatus and an image forming apparatus capable of suppressing stagnation of a developer in the developer reservoir relevant to a developer recovery member and suppress fluctuation of the liquid level of the developer in the developer reservoir relevant to a developer stirring member even when there is a change in a speed relationship between the developer carrying body and the developer stirring member. A developing apparatus includes: a developer carrying body that carries a developer and is rotationally driven; a developer stirring member that is rotationally driven and thereby stirs the developer and conveys the developer to the developer carrying body; and a developer recovery member that is rotationally driven and thereby returns and recovers thedeveloper stripped from the developer carrying body after development of the electrostatic latent image, to the developer stirring member, wherein a driving speed of the developer stirring member anda driving speed of the developer recovery member are independently controllable from each other.
