Abstract
An image forming apparatus includes an image bearing member, a developing apparatus and a toner container which replenishes the developing apparatus with toner. The developing apparatus includes a first conveyance member having a first rotational shaft and a toner replenishment port. The toner container includes a second conveyance member having a second rotational shaft and a toner discharge port. The developing apparatus and the toner container are assembled in such a manner that the first rotational shaft and the second rotational shaft are in mutually perpendicular directions, and the toner replenishment port and the toner discharge port are mutually overlapping in a vertical direction. The second conveyance member rotates in a direction whereby the toner is discharged from the toner discharge port to the toner replenishment port at a position on an upstream side of the toner replenishment port in terms of the toner conveyance direction.
