The coupling member includes a supporting portion and an engaging portion. The engaging portion is configured and positioned to displace in an inward direction with the supporting portion as the engaging portion enters a hollow cylindrical driving member of an assembly of the image forming apparatus, and is also configured and positioned to engage with a slot of the hollow cylindrical driving member when the supporting portion elastically restores in an outward direction. The engaging portion includes a rotational force receiving portion capable of being abutted in a circumferential direction of the hollow cylindrical driving member to receive a rotational drive force from the hollow cylindrical driving member to rotate the main body with the toner discharging portion.
