ABSTRACT:
In a sheet-supply device, a substantially T-shaped cutaway portion is provided in a projected portion, which is provided to an inclined wall and at a position corresponding to a sheet-supply roller near a lower end of the inclined wall that holds a stack of sheets loaded to a hopper portion. A first friction member is slidably supported in the cutaway portion so as to slide along the inclined wall from a downstream, normal position to an upstream position in a sheet feed direction. The first friction member includes a base portion and a pad portion, the pad portion is made of corkrubber and adhered to a surface of the base portion. A frictional coefficient μ of the pad portion is relatively high, i.e., frictional coefficient between adjacent sheets (approximately 0.6)≦μ≦1.0.
