An image forming apparatus includes an apparatus body including a photosensitive drum, a developing container, and a developing roller, and a toner cartridge including a toner storage chamber provided with a discharge port, a filter, and an air chamber provided with an inlet port. The apparatus body includes a pump, a first connecting portion including a passage through which the air supplied from the pump and sent toward the air chamber passes, and a second connecting portion including a passage through which the toner discharged from the discharge port together with the air and conveyed toward the developing container passes. In a case where the toner cartridge is detached from the apparatus body, connection between the first connecting portion and the inlet port is released such that the inlet port is opened before connection between the second connecting portion and the discharge port is released.
