摘要:
An image forming apparatus including an image forming unit, a discharger, and a presser including a swingable member and a contact member is provided. The contact member is partially attached to the swingable member in a condition to create clearance between an unattached part and the swingable member. Weights of the contact member and the swingable member affect the sheet when the recording medium contacts the contact member and the contact member is moved to swing upward along with the swingable member by the recording medium. Resilient force is provided by the contact member to affect the recording medium when the recording medium contacts the contact member and the contact member is moved in a direction to narrow the clearance.

An image forming apparatus is provided that includes an image forming unit disposed in a main body and configured to form an image on a recording medium, an output tray provided in the main body and configured to receive the recording medium having an image formed thereon, and an ejection device provided in the main body and configured to eject the recording medium to the output tray. The apparatus may further include a movable sheet guiding member movably attached to the main body and a stationary sheet guiding member disposed downstream of the movable sheet guiding member in a recording medium ejection direction and above the output tray. The movable sheet guiding member can press a recording medium ejected from the ejection device downward, and the stationary sheet guiding member can protrude from the main body.
