An image forming apparatus includes: an apparatus body; a photosensitive drum defining an axis extending in a first direction; a support member movable between an inside position and an outside position relative to the apparatus body; a cleaner for removing waste toner from the photosensitive drum; a first conveyer for conveying the waste toner in the first direction; a conveying unit; and a container for storing the waste toner conveyed by the conveying unit. The conveying unit includes a second conveyer for conveying the waste toner conveyed by the first conveyer in a second direction intersecting with the first direction; and a conveying pipe accommodating the second conveyer and connectable to the container. The conveying pipe includes a shutter for opening and closing a conveyer-side opening formed in a downstream end portion of the conveying pipe in the second direction.
