Image forming apparatus

An image forming apparatus comprising:

• a main body configured to form an image on paper;
• a post-printing processing device located above the main body and configured to perform post-printing processing on paper ejected from the main body;
• and
• a paper exit part that is located on a side surface of the post-printing processing device and to which paper is ejected, wherein
• the post-printing processing device includes:
• a paper inlet port via which the paper ejected from the main body is conveyed;
• and
• a conveyance device that conveys the paper conveyed via the paper inlet port into the post-printing processing device to a first position in a forward direction of the post-printing processing device and conveys the paper from the first position in a transverse direction perpendicular to the forward direction to eject the paper to the paper exit part,
• the paper exit part includes:
• a movable paper exit tray;
• a support that supports the movable paper exit tray in a manner that the movable paper exit tray is movable in an up-down direction;
• and
• a driving mechanism that causes the movable paper exit tray to move upward or downward,
• the support extends to a lower part of the main body, and
• the support supports the movable paper exit tray in a manner that the movable paper exit tray is movable downward to the lower part of the main body.
