An image forming apparatus configured to form an image on a sheet, the image forming apparatus comprising:
- an apparatus body including a first opening;
- a first cartridge including a developing roller configured to bear toner, the first cartridge being configured to be attached to and detached from the apparatus body through the first opening;
- a second cartridge including a storage portion configured to store the toner, the second cartridge being configured to be attached to, in a first direction, and be detached from, in a second direction opposite to the first direction, the first cartridge attached to the apparatus body;
- a first cover supported so as to be opened and closed with respect to the apparatus body, configured to move between a first closed position and a first open position, and including a second opening, the first closed position being a position in which the first cover covers a portion of the first opening, the first open position being a position in which the first cover opens the portion of the first opening;
- and
- a second cover configured to move between a second closed position in which the second cover covers the second opening of the first cover positioned in the first closed position and a second open position in which the second cover opens the second opening, the second cover, in the second closed position, overlapping with the first cover positioned in the first closed position when viewed in the first direction, the second cover being disposed downstream of the first cover in the second direction,
- wherein in a case where the first cover is positioned in the first open position and the second cover is positioned in the second open position, a first area of the first opening is opened when viewed in the first direction,
- wherein in a case where the first cover is positioned in the first closed position and the second cover is positioned in the second open position, a second area, of the first opening, smaller than the first area is opened through the second opening when viewed in the first direction,
- wherein the second area is included in the first area,
- wherein a whole of the first cartridge attached to the apparatus body is disposed in the first area when viewed in the first direction,
