ABSTRACT:
A recording medium feeder includes: a tray on which a plurality of recording medium are to be stacked; a feed roller that feeds the recording medium stacked on the tray; a first friction member provided on the tray and having high friction coefficient; and a second friction member provided on the tray at a position opposing the feed roller and having low friction coefficient that is lower than the friction coefficient of the first friction member, wherein the first friction member is configurable to be in one of positions of a protruded position in which a surface of the first friction member is protruded from a surface of the second friction member towards the feed roller and a retracted position in which the surface of the first friction member is arranged to be not higher than the surface of the second friction member.
