    • A developing device has a housing including a toner container containing toner, and a developing unit. The developing unit includes a developing roller and a photoconductive drum, and a barrier member including a toner supply window. The barrier member is combined with the housing to separate the toner container and the developing unit from each other. The developing unit also includes a blocking film that is attached to the barrier member to block the toner supply window. An end of the blocking film is exposed outside the housing through an opening formed in a sidewall of the housing. A bottom surface and first and second side surfaces of the barrier member are attached to a bottom surface and first and second side surfaces of the housing by using a welding process, and a distance between the first and second side surfaces of the barrier member and a distance between the first and second side surfaces of the housing increase from bottom to top.
    • 显影装置具有包括容纳调色剂的调色剂容器的壳体和显影单元。 显影单元包括显影辊和感光鼓,以及包括调色剂供应窗的阻挡构件。 阻挡构件与壳体组合以将调色剂容器和显影单元彼此分离。 显影单元还包括附着到阻挡构件以阻挡调色剂供应窗口的阻挡膜。 阻挡膜的端部通过形成在壳体的侧壁中的开口暴露在壳体的外部。 阻挡构件的底表面和第一和第二侧表面通过使用焊接工艺附接到壳体的底表面和第一和第二侧表面,并且阻挡构件的第一和第二侧表面之间的距离和 壳体的第一和第二侧表面之间的距离从底部向上增加。
