    • A developing unit provided in an image forming apparatus includes a regulating member that improves developer layer regulation performance. The developing unit is configured to feed developer to a photoconductor, on which an electrostatic latent image is formed, to form an image. The regulating member of the developing unit includes a bending portion contacting an outer peripheral surface of a developing device provided in a frame of the developing unit. The width of the regulating member is variable to increase rearward from the bending portion. The regulating member may further include an extension portion extending from the bending portion. Sealing members may be attached to both ends of the frame of the developing unit so as to contact the respective ends of the bending portion.
    • 设置在图像形成装置中的显影单元包括改善显影剂层调节性能的调节构件。 显影单元构造成将显影剂供给到其上形成有静电潜像的感光体,以形成图像。 显影单元的调节构件包括与设置在显影单元的框架中的显影装置的外周表面接触的弯曲部分。 调节构件的宽度可以从弯曲部向后方增大。 调节构件还可以包括从弯曲部分延伸的延伸部分。 密封构件可以附接到显影单元的框架的两端,以便与弯曲部分的各个端部接触。
