Image forming apparatus having developing units that can be re-supplied with developer from resupply packages

An image forming apparatus for forming an image onto a recording medium, comprising:

• (i) a plurality of developing units that are aligned in a first direction intersecting with a gravity direction, the plurality of developing units including
• (i-i) a first developing unit having a first developer accommodating portion configured to accommodate a first developer and a first developing roller configured to carry the first developer;
• (i-ii) a second developing unit having a second developer accommodating portion configured to accommodate a second developer and a second developing roller configured to carry the second developer;
• and
• (i-iii) a third developing unit having a third developer accommodating portion configured to accommodate a third developer and a third developing roller configured to carry the third developer,
• (ii) an apparatus body including a discharge roller configured to discharge the recording medium to an outside of the image forming apparatus in a discharge direction along the first direction;
• and
• (iii) a plurality of developer containers that are aligned in a second direction intersecting both the first direction and the gravity direction and that are independently attachable and detachable with respect to the apparatus body, the plurality of developer containers including:
• (iii-i) a first developer container configured to accommodate the first developer;
• (iii-ii) a second developer container configured to accommodate the second developer;
• and
• (iii-iii) a third developer container configured to accommodate the third developer,
• wherein in a case where one end and the other end of the apparatus body in the second direction are defined as a first end and a second end, respectively, and a downstream end of the apparatus body in the discharge direction is defined as a front end, the apparatus body includes:
• a first conveyance passage through which the first developer is conveyed from the first developer container towards the first developer accommodating portion, the first conveyance passage including a first portion provided on a side of the first end of the apparatus body in the second direction;
• a second conveyance passage through which the second developer is conveyed from the second developer container towards the second developer accommodating portion, the second conveyance passage including a second portion provided on the side of the first end of the apparatus body in the second direction;
• and
• a third conveyance passage through which the third developer is conveyed from the third developer container towards the third developer accommodating portion, the third conveyance passage including a third portion provided on the side of the first end of the apparatus body in the second direction,
• wherein the first developer container is positioned the closest to the first end of the apparatus body among the plurality of developer containers in the second direction,
• wherein the first developer container, the second developer container, and the third developer container are aligned in this order in a direction from the first end to the second end with respect to the second direction, the first developer container and the second developer container are adjacent to each other, and the second developer container and the third developer container are adjacent to each other,
• wherein the first developer container, the second developer container, and the third developer container are provided on a side of the front end of the apparatus body in the first direction, and
• wherein the first portion of the first conveyance passage overlaps with the third portion of the third conveyance passage when viewed in the gravity direction.
