Abstract
A recording-material-feeding device includes a stacking portion that holds a stack of recording materials, a lifting member that moves the stacking portion up and down between a feeding position at which a recording material is fed and a refilling position at which refill recording materials are supplied, a suction member that draws one or more recording materials by suction with a negative pressure, a negative-pressure-generating member that generates the negative pressure, and a stopping member that stops an edge of the stack of recording materials on the stacking portion and includes a sealing member that maintains the level of the negative pressure. The sealing member moves up and down between a retracted position at which refill recording materials are supplied and a sealing position at which the level of the negative pressure is maintained, the sealing member moving with the up-and-down movement of the stacking portion.
