Claims

[Claims for Utility Model Registration] 1. In a device in which a plurality of developing units having different developers are removably installed around an image carrier to obtain a multicolor image on the image carrier, At least two or more storage sections into which units can be attached, and an instruction provided in the vicinity of the storage sections to indicate that at least one of the development units is not attached to the storage section in conjunction with attachment or detachment of the development unit. 1. A developing unit storage device for an image forming apparatus, comprising an indicating means and a locking mechanism that engages when the indicating means is activated and holds the opening/closing portion of the main body in an open state. 2. An indicating means is movably provided on a side wall of the housing, and when the developing unit is not installed in the housing, the indicating means is protruded into the housing space, while when the developing unit is installed in the housing, the indicating means is movably provided on the side wall of the housing. a device guide that is pressed against the developing unit so as to be flush with the developer unit; an opening/closing portion is a main body cover; and a locking mechanism is in contact with the mounting guide that protrudes into the storage space when the main body cover is closed. The developing unit storage device for an image forming apparatus according to claim 1, characterized in that the developing unit storage device is a projection attached to the main body cover so as to be in contact with the main body cover.
