A copier, printer or similar image forming apparatus operable with a supply such as a developer cartridge being loaded in a body thereof. A door forms a part of a housing portion of the apparatus body and is provided with an opening for loading and unloading a supply and an openable lid for covering and uncovering the opening. Even when the lid is opened, the operation of the apparatus is not interrupted. Simple and safe replacement of a supply is insured and, yet, a supply is prevented from contaminating the apparatus when loaded and unloaded.
