detecting the amount of stacked paper in the selected discharging bin. When theselected discharging bin is changed to a newly selected discharging bin, the dischargingbins are moved by the bin elevating motor, whereby the sensor detects the amount ofstacked paper in the newly selected discharging bin to which discharging can beperformed after the moving. Subsequently, the sensor directs the start of imageformation.
