图像形成装置、显影装置和图像形成方法
摘要：
一种图像形成装置、显影装置以及图像形成方法，使用表面设有规则的凹凸的调色剂担持滚筒，防止因密封部件上附着调色剂而引起调色剂泄漏或镀膜等问题。通过斜齿轮对(421)且利用马达(422)旋转驱动连结于显影滚筒(44)的旋转轴(440)。在旋转轴(440)上抵接有弹性金属板即电极板(140)，且向(－X)方向对显影滚筒(44)施力。如果马达(422)旋转，则显影滚筒(44)会因产生于旋转轴(440)上的推力而向X方向移位。此时，由于设置于显影滚筒(44)表面的凸部斜向滑擦密封部件(47)表面，所以固着于密封部件(47)上的调色剂能够被刮离下来。
摘要（英）：

The invention relates an image forming apparatus, a developing device and an image forming method, using a toner holding roller with a surface provided with a regular concave portion and a convex portion to prevent toner from being attached to a sealing member, which causes the leakage of the toner and film coating problem. A rotary shaft (440) connected with a developing roller (44) is driven by a bevel wheel pair (421) and the rotation of a motor (422). An elastic metal plate, namely an electrode plate (140) is leaned against the rotary shaft (440) exerting force on the developing roller (44) in (-X) direction. If the motor (422) rotates, the developing roller (44) is displaced in the X direction due to the thrust force generated on the rotary shaft (440). At the moment, as the convex portion on the surface of the developing roller (44) is inclined to rub the surface of the sealing member (47), the toner fixedly attached to sealing member (47) can be scraped off.
