Image forming apparatus having a stacking portion with first and second surfaces

An image forming apparatus includes a stacking portion which is a part of a top surface of an exterior of the image forming apparatus. The stacking portion is positioned downstream of a discharging outlet in a discharging direction and on which the recording material discharged from the discharging outlet is stacked and includes a first surface on which the recording material discharged from the discharging outlet is stacked, and a second surface which is positioned outward with respect to the discharging outlet in a width direction orthogonal to the discharging direction. A supplying inlet is located below the first surface, wherein a downstream end of the first surface is positioned downstream of a downstream end of the second surface in the discharging direction, and wherein the first surface is rotatable to expose the supplying inlet.
