    • A developer cartridge includes a developer cartridge case for accommodating a developer, a developing roller, a toner layer thickness control blade, and a side sealing member. The developing roller is supported by the developer cartridge case such that a circumferential surface thereof is exposed to an outside of the developer cartridge case along a width direction. The toner layer thickness control blade includes a blade body portion made of a metallic plate. A tip portion of the blade body portion is disposed at a sliding portion of the developing roller and the side sealing member so as to contact with the side sealing member. A frictional heat generated at the sliding portion is released to the outside of the developer cartridge case through the blade body portion in order restrain a leak of the developer as much as possible.
    • 显影剂盒包括用于容纳显影剂的显影剂盒壳体,显影辊,调色剂层厚度控制刮板和侧密封件。 显影辊由显影剂盒壳体支撑,使得其周向表面沿着宽度方向暴露于显影剂盒壳体的外部。 调色剂层厚度控制刮板包括由金属板制成的刀片主体部分。 叶片主体部分的尖端部分设置在显影辊和侧面密封件的滑动部分处以与侧面密封件接触。 在滑动部分产生的摩擦热通过叶片主体部分释放到显影剂盒壳体的外部,以尽可能地抑制显影剂的泄漏。

    • A layer-thickness regulating member includes a thin plate member and a projection member provided on a free edge portion of the thin plate member. A leak preventing members include a first seal member and a second seal member. The first seal member includes a first downstream portion disposed adjacent to the projection member on a front surface of the thin plate member, and a first upstream portion extending upstream of the first downstream portion. The second seal member includes a second downstream portion, and a second upstream portion which extends upstream of the second downstream portion. The second upstream portion includes a covered portion covered with the first upstream portion, an opposed portion disposed adjacent to the covered portion and opposed to the adjacent portion of the projection member and an exposed portion extending upstream of the covered portion and the opposed portion.
    • 层厚调节构件包括薄板构件和设置在薄板构件的自由边缘部分上的突出构件。 泄漏防止构件包括第一密封构件和第二密封构件。 第一密封构件包括在薄板构件的前表面上邻近突出构件设置的第一下游部分和在第一下游部分的上游延伸的第一上游部分。 第二密封构件包括第二下游部分和在第二下游部分的上游延伸的第二上游部分。 第二上游部分包括被第一上游部分覆盖的被覆部分,与覆盖部分相邻并与突出部件的相邻部分相对的相对部分以及延伸到被覆部分和相对部分的上游的暴露部分。
