For example, Japanese unexamined patent application publication No. 2010-26299 describes an image-forming device having a drawer that can be pulled out from the body of the device, and a plurality of developer cartridges that are detachably mounted in the drawer. Each developer cartridge is provided with a grip part by which a user can hold the developer cartridge. The grip part can be displaced between a stored position in which the grip part is retracted into the drawer, and a grippable position in which the grip part sticks out enough for the user to grasp.
