摘要： A photosensitive drum protecting device for use in a color electrophotographic printer is provided. The printer, in which developing device cartridges of various colors including photosensitive drums and developing rollers are installed, and a printing path contacting the photosensitive drums is formed, includes a photosensitive drum protecting device that simultaneously exposes or protects each of the photosensitive drums. All of the photosensitive drums disposed at front end portions of the developing device cartridges are covered by just one photosensitive drum protecting device. Thus, the complexity of the printer is reduced and the printer can be made more compact.

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.
