Image forming apparatus

An image forming apparatus configured to form an image on a sheet, comprising:

• an apparatus body including:
• a first developing unit including a first developing container configured to accommodate a first toner, and a first developing roller configured to bear the first toner;
• and
• a second developing unit including a second developing container configured to accommodate a second toner, and a second developing roller configured to bear the second toner,
• a first toner container configured to accommodate the first toner and attachably and detachably supported on the apparatus body, the first toner container being configured to supply the first toner together with air toward the first developing container;
• a second toner container configured to accommodate the second toner and supported attachably and detachably on the apparatus body, the second toner container being configured to supply the second toner together with air toward the second developing container, the second toner container being aligned in a first direction with the first toner container;
• and
• a pump unit including:
• a first pump configured to convey air toward the first toner container, and
• a second pump configured to convey air toward the second toner container,
• wherein the first developing unit and the second developing unit are aligned in a second direction orthogonal to the first direction,
• wherein the first toner container and the second toner container are disposed closer to the first developing unit than to the second developing unit in the second direction, and
• wherein the pump unit is disposed so as to be overlapped with the first developing unit when viewed in a third direction perpendicular to both the first direction and the second direction.
