US07769316B2 Developing unit and process cartridge for reducing toner scattering, and image forming apparatus using the same 有权
用于减少调色剂散射的显影单元和处理盒，以及使用其的成像装置

Developing unit and process cartridge for reducing toner scattering, and image forming apparatus using the same
Abstract:
A developing unit for developing a latent image formed on an image carrier includes a developer carrier, a developer regulator, and a sealing member. The developer carrier bears a developer, and is disposed facing the image carrier at a first position. The developer regulator regulates an amount of the developer, and is disposed facing the developer carrier at a second position upstream of the developer carrier in a moving direction thereof relative to the first position. The sealing member comes into contact with the image carrier at a third position upstream of the image carrier in a moving direction thereof relative to the first position. Therefore, gas is prevented from flowing from an outside area of the developing unit into an area defined by the second position to the third position.
Abstract(Chinese):

用于显影形成在图像载体上的潜像的显影单元包括显影剂载体，显影剂调节剂和密封构件。 显影剂载体带有显影剂，并且在第一位置处被布置成面向图像载体。 显影剂调节剂调节显影剂的量，并且相对于第一位置在显影剂载体的上游的第二位置处朝着显影剂载体的移动方向布置。 密封构件在图像载体的上游第三位置处与图像载体相对于第一位置在其移动方向上接触。 因此，防止气体从显影单元的外部区域流入由第二位置到第三位置限定的区域。
