    • A powder feed device includes a casing having an opening for receiving a powder from a powder housing portion housing the powder, at least an inner side of the casing having a cylindrical shape; a transport member that is arranged in the casing, extends in a powder transport direction, and rotates and transports the powder to the fed body; and a shutter member that is arranged at a closed position for closing the opening, receives a force from the transport member by its rotation, and moves to an open position for opening the opening. The transport member includes a transport portion that contributes to the powder transport, and a non-transport portion that does not contribute to the powder transport, and handles the movement of the shutter member to the open position. The shutter member moves to the open position when receiving an effect of the non-transport portion.

    • An image forming device includes: an image carrier that carries an image; a development unit that develops, with toners, a latent image written on the image carrier; an intermediate transfer member to which the toner images formed on the image carrier by the development unit are primarily transferred; and a fixing unit that fixes, to paper, the toner images secondarily transferred from the intermediate transfer member. The image carrier and the intermediate transfer member are unitized to configure an image forming unit, and the image forming unit is disposed in a space sandwiched between the development unit and the fixing unit. The image forming unit further includes a loading/unloading allowing unit that allows the loading/unloading of the image forming unit.
