US09141035B2 Developing device forming toner image by feeding toner toward electrostatic latent image formed on circumferential surface of photosensitive drum, and image forming apparatus including the same 有权
通过将调色剂供给到形成在感光鼓的圆周表面上的静电潜像来形成调色剂图像的显影装置，以及包括该感光鼓的图像形成装置

Developing device forming toner image by feeding toner toward electrostatic latent image formed on circumferential surface of photosensitive drum, and image forming apparatus including the same
Abstract:
A developing device includes a developing roller, a regulating blade, and seal members. The regulating blade extends in a rotation axis direction of the developing sleeve, is disposed opposite to a circumferential surface of the developing sleeve, and regulates a quantity of the toner present on the circumferential surface of the developing sleeve. The seal members are disposed opposite to the circumferential surface of the developing sleeve without being in contact with both ends of the developing sleeve in the rotation axis direction, and inhibit the toner on the circumferential surface from moving to the rotation axis direction ends by magnetic brushes formed between the magnet roller and the seal members. An inner surface part of each seal member which is opposite to the circumferential surface of the developing sleeve has root parts which have crest parts formed in a serrated shape.
Abstract(Chinese):

显影装置包括显影辊，调节片和密封件。 调节刀片沿着显影套筒的旋转轴线方向延伸，与显影套筒的圆周表面相对设置，并且调节存在于显影套筒的圆周表面上的调色剂的量。 密封构件与显影套筒的圆周表面相对设置，而不与显影套筒的旋转轴线方向的两端接触，并且阻止圆周表面上的调色剂通过磁刷移动到旋转轴线方向 形成在磁辊和密封构件之间。 每个密封构件的与显影套筒的圆周表面相对的内表面部分具有形成为锯齿形状的顶部部分的根部。
