Image forming apparatus

An image forming apparatus comprising:

• an apparatus main body;
• a plurality of photosensitive drums which are aligned in an alignment direction;
• a belt which is provided to oppose the plurality of photosensitive drums;
• and
• a holder which is configured to collectively hold the plurality of photosensitive drums, and configured to be moved in the alignment direction between an outer position located at an outside of the apparatus main body and an inner position located at an inside of the apparatus main body,
• wherein the holder includes:
• a first handle unit which is provided at an upstream side of the photosensitive drums in a mounting direction of the holder moved from the outer position to the inner position;
• a second handle unit which is provided separately from the first handle unit at a downstream side in the mounting direction;
• and
• an interfered portion which is configured to interfere with the apparatus main body,
• wherein the second handle unit is supported by the holder to be movable between a protrusion position where the second handle unit protrudes from a top portion of the plurality of the photosensitive drums and a retreat position where the second handle unit retreats below the top portion of the plurality of the photosensitive drums, and
• wherein the interfered portion is configured to interfere with the apparatus main body to cause the second handle unit to be displaced from the protrusion position to the retreat position, and when the holder is moved in the mounting direction, before the second handle unit reaches the belt, the interfered portion interferes with the apparatus main body.
