A toner container is manually attachable to a mount of a body of an image forming apparatus horizontally in an attachment direction and detachable from the mount horizontally in a detachment direction. The toner container includes a bottom portion and a projection. The projection protrudes downward to a lowest position in the bottom portion of the toner container in a posture when the toner container is attached to and detached from the mount, and slides on a surface of the mount when the toner container is attached to and detached from the mount. A length from a downstream end of the bottom portion in the attachment direction to the projection is within a range of 37.5 to 80 mm.
