<p>PROBLEM TO BE SOLVED: To provide an image forming device capable of coping with stacking of many paper sheets to a paper discharging tray. SOLUTION: When the amount of paper sheets on a loading plate 32 of a paper feeding tray 31 is decreased smaller than the specified amount, the situation is detected by a paper sheet surface detecting sensor 39. The loading plate 32 is pressed up by a signal, the upper surface of the paper sheet is pressed to a pick up roller 35 by specified pressure. However, since that the amount of paper sheets is decreased is that the paper discharging amount to a paper discharging tray 21 is increased, the paper discharging tray 21 is lowered by the signal of the paper sheet surface detecting sensor 39, and the suitable rising and lowering control of the paper sheet discharging tray 21 is performed.</p> |
