An image forming apparatus includes an apparatus body, an image forming portion, a sheet feeding port, a bypass tray, a rotation support, and a temporary retainer. The image forming portion is disposed in the apparatus body to form an image on a recording medium. The sheet feeding port is disposed upstream from the image forming portion of the apparatus body in a sheet feeding direction. The bypass tray is disposed to be storable in the apparatus body. The bypass tray loads the recording medium to be fed toward the sheet feeding port. The rotation support supports the bypass tray. The temporary retainer positions the bypass tray both in a vertical direction relative to the sheet feeding port and in a perpendicular direction perpendicular to the sheet feeding direction. The temporary retainer temporarily retains the bypass tray.
