Image forming apparatus

An image forming apparatus comprising:

• an image forming unit configured to form an image on a recording sheet;
• a sheet receiving portion configured to receive the recording sheet having the image;
• an ejection roller configured to rotate in a forward direction to eject the recording sheet fed from the image forming unit to the sheet receiving portion, and to rotate in a reverse direction to return the recording sheet to the image forming unit;
• a restriction member configured to move between a restriction position where the restriction member protrudes farther in a sheet ejection direction than a peripheral surface of the ejection roller and a retracted position where the restriction member is retracted from the restriction position;
• and
• a supporting member for supporting the restriction member movably between the restriction position and the retracted position, the supporting member having a support surface, the restriction member being configured to slide on the support surface,
• wherein one of the restriction member and the support surface of the supporting member includes a first engaging portion and the other one of the restriction member and the support surface of the supporting member includes a second engaging portion configured to engage the first engaging portion.
