Abstract
In a paper feed unit, a plurality of stacking plates are stacked in a box. The stacking plates can stack paper of different sizes and are stacked on each other. Paper stored on each stacking plate is taken out by a pickup roller, a paper feed roller, and a separation roller. These rollers can be moved to positions for taking out paper stored on the stacking plates. Taken-out paper is guided to a photosensitive drum through guide plates.
