    • A development apparatus and an image forming apparatus using the same are provided to apply desired amount of electric charge by agitating a stray toner. A development vessel(3) accommodates a developer consisting of a toner and a carrier. A developer retaining body(4) is installed at the development vessel, and faces an image retaining body to maintain the developer. A developer supplier(5) is installed inside the development vessel, supplies the developer to the developer retaining body. The developer agitator(6) is installed at a different chamber from where the developer supplier is installed in the development vessel, and agitates the developer to supply to the developer supplier. A developer recovering unit(7) is installed at the rotational direction downstream of the image retaining body, recovers the stray toner, and returns the stray toner to the developer agitator.

    • A developing machine is provided to stably exhaust a developer from an exhaust hole without increasing a size of the developing machine. A carrying shaft is installed and rotated in a developing machine(12). A developing carrying part of a spiral shape is formed in the outer circumference of the carrying shaft. The developing carrying part carries a developer in an axis direction along the rotation of the carrying shaft. An exhaust hole(64) is installed in an inner wall surface opposite to the carrying shaft. The exhaust hole(64) exhausts the developer from the inner wall surface. A storing chamber(62) stores the developer exhausted from the exhaust hole(64). An opening and closing member(60) of a plate shape opens and closes the exhaust hole(64) along the rotation of a rotary body(11) by self-weight. The opening and closing member(60) is in an opened state in a developing position. The developing machine(12) is maintained in the rotary body(11), and is successively opposite to the developing position of a photosensitive drum(102) by the rotation of the rotary body(11). The opening and closing member(60) has an opening and closing point in a lower end part of the opening and closing member(60) in the developing position.
    • 提供了一种显影机,用于在不增加显影机尺寸的情况下从排气孔稳定地排出显影剂。 承载轴在显影机(12)中安装和旋转。 在承载轴的外周形成螺旋状的显影承载部。 显影承载部件沿着承载轴的旋转沿轴向携带显影剂。 排气孔(64)安装在与承载轴相对的内壁面上。 排气孔(64)从内壁表面排出显影剂。 存储室(62)存储从排气孔(64)排出的显影剂。 板状的打开和关闭构件(60)通过自重将旋转体(11)的旋转打开和关闭排气孔(64)。 打开和关闭构件(60)在显影位置处于打开状态。 显影机(12)保持在旋转体(11)中,并通过旋转体(11)的旋转而与感光鼓(102)的显影位置相对。 打开和关闭构件(60)在处于显影位置的打开和关闭构件(60)的下端部具有开闭点。
