摘要： An apparatus to detect the remaining amount of developer in a developing unit is provided. The apparatus includes a light emitting prism and a light receiving prism placed opposite to each other in a developer store space of the developing unit and forming a light emitting path and a light receiving path, respectively. A light emitting element irradiates light through the light emitting prism, and a light receiving element receives a light signal through the light receiving prism. An antistatic agent is coated on a light emitting window of the light emitting prism and a light receiving window of the light receiving prism, respectively, to substantially prevent developer from attaching on the light emitting window and the light receiving window. Because the developer is not stuck on the light receiving window and the light emitting window to which the light signal is transmitted, an accurate light signal may be transmitted from the light emitting window to the light receiving window, thereby substantially preventing printing defects caused by detection errors from occurring.
摘要翻译：提供一种用于检测显影单元中的显影剂剩余量的装置。该装置包括分别在显影单元的显影剂存储空间中彼此相对设置的发光棱镜和光接收棱镜，并分别形成发光路径和光接收路径。发光元件通过发光棱镜照射光，并且光接收元件通过光接收棱镜接收光信号。防静电剂分别涂覆在发光棱镜的发光窗口和光接收棱镜的光接收窗口上，以基本上防止显影剂附着在发光窗口和光接收窗口上。由于显影剂不粘附在光接收窗口和发出光信号的发光窗口，因此可以将准确的光信号从发光窗口传输到光接收窗口，从而基本上防止由检测引起的打印缺陷发生错误

摘要： In an image forming apparatus, a developing unit includes an inlet cover for opening and closing a toner inlet formed in an outer casing of the developing unit, and an outlet cover for opening and closing a toner outlet. A toner cartridge includes a toner feeding roller for selectively opening and closing a toner feeding port formed in an outer casing of the toner cartridge, a recovery cover for opening and closing a toner recovery port formed in an outer casing of the toner cartridge in relative movement with the outlet cover during mounting and removal with respect to the developing unit, and a supporting projection for restricting and opening and closing one end of the inlet cover during mounting and removal of the toner cartridge with respect to the developing unit. As a result of this arrangement, a user does not have to perform additional steps to open and close the toner feeding path and the toner recovery path, and accordingly can use the image forming apparatus with more convenience.
