Abstract
An image forming apparatus includes: a tray; a delivery roller; a paper feeding roller; a guide member; a lifting/lowering mechanism; a first detector; and a controller. The controller executes paper feeding processing of feeding a sheet of paper delivered from the tray by rotating the paper feeding roller, executes, during the paper feeding processing, retry processing of resuming the paper feeding processing after stopping the paper feeding processing when the fed sheet of paper is not detected by the first detector, and executes, during the retry processing, lifting and lowering processing of lifting and lowering the tray within a predetermined range after stopping the paper feeding processing and before resuming the paper feeding processing. The predetermined range is a range in which an uppermost sheet of paper placed on the tray can abut on the guide member when the uppermost sheet of paper is delivered by the delivery roller.
