    • PROBLEM TO BE SOLVED: To provide a developing device capable of preventing a sheet member from being cut when the sheet member is pulled out to open an opening. SOLUTION: A flexible presser plate 81 (press means) which presses the free end 52D side of a backward path 52C against a forward path 52B is provided for the sheet member 52 for sealing an inlet side opening 51. The presser plate 81 presses the backward path 52C tof the sheet member 52 toward the forward path 52B side, so that the backward path 52C is prevented from floating out of the forward path 52B and the developer is prevented from entering an area between the backward path 52C and the forward path 52B and an area between the sheet member 52 and an upper housing 33, or the like. When the sheet member 52 is pulled out, the top end side 81B of the presser plate 81 opens in the direction of an arrow Ca direction (Fig.7(a)) and an aperture is formed between the backward path 52C and the forward path 52B of the sheet member 52 (Fig.7(b)). Even when the developer is sandwiched, the developer is removed on the pulling-out of the sheet member 52. COPYRIGHT: (C)2010,JPO&INPIT
    • 要解决的问题:提供一种当片材被拉出以打开开口时能够防止片材被切割的显影装置。 解决方案:为了密封入口侧开口51而设置用于将后向路径52C的自由端52D侧压靠前进路径52B的柔性压板81(按压装置)。压板81 将片状构件52的向后路径52C朝向正向路径52B侧按压,使得防止向后路径52C从前向路径52B浮出,并且防止显影剂进入到后向路径52C和前方路径52C之间的区域 路径52B以及片状构件52和上部壳体33之间的区域等。 当片材52被拉出时,压板81的顶端侧81B沿箭头Ca方向(图7(a))的方向开口,并且在后向路径52C和前进路径 52B(图7(b))。 即使当显影剂被夹持时,在片材52的拉出时移除显影剂。版权所有(C)2010,JPO&INPIT

    • PROBLEM TO BE SOLVED: To prevent toner leakage during the distribution of a toner supply container, without increasing the force required to open or close a shutter, while preventing toner from entering the gap between the toner supply container and an image forming apparatus. SOLUTION: An elastic seal is attached to the toner supply container, in a manner of surrounding the opening of its outlet, and the outlet of the toner supply container is sealed with a freely peelable sealing film. As a result, toner is prevented, from scattering during both the distribution of the toner supply container and the supply of toner. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:为了防止调色剂供应容器分配期间的调色剂泄漏,而不增加打开或关闭快门所需的力,同时防止调色剂进入调色剂供给容器和成像设备之间的间隙 。 解决方案:弹性密封件以围绕其出口的开口的方式附接到调色剂供应容器,并且调色剂供应容器的出口用可自由剥离的密封膜密封。 结果,防止调色剂在调色剂供给容器的分配和调色剂供应期间散射。 版权所有(C)2007,JPO&INPIT
