ABSTRACT:
A sheet feeding device comprises a pick roller; a push-up board; a first friction member located in a position on the push-up board opposed to the pick roller with the sheet bundle interposed therebetween; and a second friction member located in a position on the push-up board upstream in a sheet transferring direction and not opposed to the pick roller. In the sheet feeding device, the second friction member has a most protruding part which protrudes to the sheet bundle more than a sheet bundle side surface of the first friction member, and a dynamic friction coefficient of the second friction member to the sheet is larger than that of the first friction member and smaller than that of the pick roller. Accordingly, double-paper feeding can be prevented and even the last one sheet can be fed regardless types of sheets.
