ABSTRACT:
In conventional image forming apparatus, there is a type of a printer in which a developing device and a developer supplying container are separately provided and the developer supplying container is replaced individually to supply a developer that is an expendable agent. The printer of this type has an advantage that it is unecessary to replace frequently the component having a relatively long durable life, while the printer has the disadvantage that leakage of the developer easily occurs when the developer supplying container is removed from the printer main body. Therefore, an image forming apparatus capable of controlling leakage of developer is provided.
