Zusammenfassung:	Provided is an image forming apparatus, including: a manual feed tray on which a recording material is stacked; a first detecting unit; a second detecting unit arranged on an upstream side of the first detecting unit; a third detecting unit arranged on an upstream side of the second detecting unit; a fourth detecting unit detecting a length of the recording material; a display portion; and a control portion determining a size of the recording material based on detection results and causing the display portion to display a first screen displaying the determined size, wherein the control portion causes the display portion to display a second screen for designating the size, when, among the first to third detecting units, a detecting unit located on a downstream side does not detect presence of the recording material and another detecting unit located on an upstream side of the detecting unit, detects the presence.
