摘要： A developer unit of an electrophotographic image forming apparatus includes a blocking blade having a magnetic fluid and a magnet. The magnetic fluid contacts a developer roller and the metering blade to prevent a developer from flowing to both ends of the metering blade. The magnetic fluid is fixed to the magnet which applies a pressure to the magnetic fluid so that the magnetic fluid contacts the developer roller and the metering blade. Since the magnetic fluid contacts the developer, wear of elements of the developer unit can be reduced, thereby securing durability of the developer unit. Also, a wrap-around phenomenon of the developer can be prevented.
摘要翻译：电子照相图像形成装置的显影单元包括具有磁性流体和磁体的阻挡刮板。磁性流体接触显影辊和计量刀片，以防止显影剂流到计量刀片的两端。磁性流体固定在磁体上，该磁体向磁性流体施加压力，使得磁性流体接触显影辊和计量刮板。由于磁性流体与显影剂接触，所以可以减少显影剂单元的元件磨损，从而确保显影剂单元的耐久性。此外，可以防止显影剂的回绕现象。

摘要： A recovered toner classifier includes a rotatable cylindrical-shaped filter and a fur brush having a brush spirally provided on an outer peripheral surface of a rotation shaft. A non-brush region is continuously formed from the inlet of the filter for the recovered toner through the outlet of the filter for discharging the disposal toner along the axis line of the rotation shaft. The fur brush integrally rotates with the rotation shaft with a tip portion of the brush is in press-contact with an inner peripheral surface of the filter. A screw conveyer having a screw on a portion of the rotation shaft on a side of the inlet of the filter for the recovered toner is provided to convey the recovered toner to the inlet of the filter for the recovered toner.

摘要： A developing device 4 includes a developing roller 10 that faces a drum 1, a supplying roller 11 that supplies the toner to the developing roller 10, and a toner container 15 for storing the toner. A toner layer forming roller 12 contacts the developing roller 10 and rotates in the same direction as the developing roller 10. A part of the toner is transferred from the developing roller 10 to the peripheral surface of the toner layer forming roller 12 to form a toner layer. The thickness of the toner layer on the toner layer forming roller 12 is regulated by a blade 13. According to the rotation of the toner layer forming roller 12, the toner layer is carried outside the toner container 15, where the toner layer is transferred to the peripheral surface of the developing roller 10.
