    • The present invention relates to an image forming apparatus comprising: an exposing means and a developing means. The developing means comprises a plurality of developing devices, a rotating member rotatable while supporting the plurality of the developing devices, and a driving means for the rotation drive of the rotating member for selectively moving the plurality of the developing devices to the developing position such that the driving means transmits driving force to the rotating member via a gear at a drive transmitting position. An angle θe(°) formed by a straight line linking the rotation center of the rotating member and the drive transmitting position and the tangent of the image bearing member at an exposing position in the image bearing member moving direction satisfies the following relationship with the premise that an pressure angle of the gear is α(°) and the image bearing member rotating direction is positive:−α≦θe≦α.
    • 本发明涉及一种图像形成装置,包括:曝光装置和显影装置。 显影装置包括多个显影装置,在支撑多个显影装置的同时可旋转的旋转构件,以及用于旋转构件的旋转驱动的驱动装置,用于选择性地将多个显影装置移动到显影位置,使得 驱动装置通过驱动传动位置处的齿轮将驱动力传递到旋转构件。 在图像承载部件移动方向的曝光位置处,通过将旋转部件的旋转中心与驱动传递位置与图像承载部件的切线连接的直线形成的角度θe(°)满足以下关系: 齿轮的压力角为α(°),图像承载部件旋转方向为正:-α<=θe<=α。

    • An image forming apparatus having a high toner containing efficiency of a waste toner-collecting container is provided. Piled toner is broken by an vibrating imparting operation and at the same time, a toner feeding member such as a feeding screw disposed inside the toner-collecting container is rotated by changing a reciprocating operation by the vibrating impartment to a rotational operation in a direction. As a result, the piled toner which cannot be completely broken by the vibrating imparting operation is broken and fed, so that driving noise is reduced and the toner containing efficiency is improved.
    • 提供了具有含有废调色剂收集容器的效率的高调色剂的图像形成装置。 堆积的调色剂通过振动赋予操作而断裂,并且同时,通过将振动隔离物的往复运动改变为沿一个方向的旋转操作,调色剂收集容器内部的馈送螺杆等调色剂供给部件转动。 结果,通过振动赋予操作不能完全破碎的堆积的调色剂被破坏并进给,从而降低了驱动噪音并提高了调色剂的包含效率。
