An image forming apparatus includes an apparatus body including a photosensitive drum, a developing container, and a developing roller, and a toner cartridge. The toner cartridge includes 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 restricting member configured to be movable in an intersecting direction between a restricting position and an allowing position, a connecting portion communicating with a first passage, and a pump. The restricting member includes a second passage through which the air supplied from the pump to the air chamber passes, engages with the inlet port to supply the air to the air chamber in a case where the restricting member is at the restricting position, and is separated from the inlet port to open the inlet port in a case where the restricting member is at the allowing position.
