Abstract
Even if sheets are removed from the first tray 49 during the execution of a job that includes the operation of continuously discharging sheets into the first tray 49, a decrease in the alignment of sheets on the first tray 49 is suppressed. [Solution] The third light-receiving unit 510c detects the first tray 49 or the sheets stacked on the first tray 49 below the second light-receiving unit 510b. The third light-receiving unit 510c is configured to be ON if the first tray 49 or the sheets stacked on the first tray 49 are within the detection area, and OFF if the first tray 49 or the sheets stacked on the first tray 49 are not within the detection area. The stacker control unit prohibits alignment operations for sheets discharged after the third light-receiving unit 510c has been turned OFF if the third light-receiving unit 510c is turned OFF during the execution of a job that includes the operation of continuously discharging sheets to the first tray 49 by the discharge roller pair 42.
