Image forming apparatus with extended cartridge opening and cover

An image forming apparatus comprising:

• an image forming unit configured to form an image on a sheet;
• a discharging roller configured to discharge, in a discharging direction, the sheet on which the image is formed to an outside of the image forming apparatus;
• a frame provided with an opening through which the image forming unit is configured to be exposed from the frame;
• an opening and closing member configured to move between an open position in which the opening and closing member opens the opening so as to expose the image forming unit through the opening and a closed position in which the opening and closing member closes the opening so as not to expose the image forming unit through the opening, the opening and closing member having a supported portion supported by the frame so that the opening and closing member is rotatable about a rotational axis, the opening and closing member having a stacking surface on which the sheet discharged by the discharging roller is to be stacked when the opening and closing member is in the closed position;
• and
• a wall provided upstream of the stacking surface in the discharging direction and extending from the stacking surface toward the discharging roller in an upward direction when the opening and closing member is in the closed position, the wall being attached to the opening and closing member so as to be movable relative to the opening and closing member.
