Abstract
A switching controller switches from a developer replenishment prohibition mode to a developer replenishment permission mode when the replenishment detection device detects that the developer containing section does not store a prescribed amount of the developer, and from the developer replenishment permission mode to the developer replenishment prohibition mode when a prescribed operation is executed upon completion of replenishment of the developer from the developer containing bottle to the developer containing section. The developer replenishment prohibition mode prohibits the developer replenishment device from replenishing the developer to the developer containing section, while the developer replenishment permission mode permits the developer replenishment device to replenish the developer to the developer containing section.
