Abstract: A developing device unit has a developing device unit main body which rotates about a rotary shaft. Plural developing devices are disposed on the developing device unit main body. The developing devices respectively have developing device main bodies, and developing agent cartridges containing four color developing agents are respectively loaded into the developing device main bodies. The developing agent cartridges are attached/detached in a direction substantially tangential to the rotating direction of the developing device unit main body when a grip section is gripped and operated by the operator in the case where the developing agent cartridges are at a location substantially opposite an image carrier with respect to the rotary shaft.

Abstract: An image forming device that forms images by electrophotographic processes and includes a toner cartridge loading part in which three or more toner cartridges for housing toners used to form the images are loaded, wherein the toner cartridges are juxtaposed in two or more rows in a length direction or lateral direction in a toner cartridge insertion face of the toner cartridge loading part.

Abstract: Provided is an image forming apparatus that not only prevents leakage of a developer from a developing apparatus due to vibrations and the like at the time of transportation but also enables attachment of a developer leakage preventing member to a miniaturized image forming apparatus and facilitates attachment and detachment of the developer leakage preventing member at the time of use of the image forming apparatus.
