SHEET FEEDER, IMAGE FORMING APPARATUS INCORPORATING THE SHEET FEEDER, AND METHOD OF REMOVING DISCHARGE PRODUCTS IN THE IMAGE FORMING APPARATUS

摘要

A sheet feeder, which is incorporated in an image forming apparatus, includes an attraction body disposed facing a bundle of sheets, a charger to charge the attraction body to electrostatically attract an uppermost sheet of the bundle of sheets to the attraction body, a liquid supplier to supply a liquid to dissolve discharge products to the attraction body, and a liquid remover to remove the liquid from the attraction body. Further, a method of removing discharge products includes counting the number of sheets fed from a sheet container, 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, removing the discharge products from a surface of an attraction body, and resetting the number of sheets or further turning off the power supply.
