A sheet feeder (200), which is incorporated in an image forming apparatus (100), includes an attraction body (2), a charger (3, 4) to charge the attraction body (2) to electrostatically attract an uppermost sheet (1a) to the attraction body (2), a liquid supplier (131) to supply a liquid (R) to dissolve discharge products to the attraction body (2), and a liquid remover (132) to remove the liquid (R) supplied by the liquid supplier (131) from the attraction body (2). Further, a method of removing discharge products includes counting the number of sheets fed from a sheet container (52), determining that the number of sheets reaches a predetermined threshold value, confirming that a current time falls within a predetermined period of time or receiving a turn off signal to turn off a power supply (4), removing the discharge products from the attraction body (2), and resetting the number of sheets. |
