ABSTRACT:
A paper feeding device which extracts from a cassette accommodating a stack of sheets such sheets one at a time and feeds them to the next step, namely an image forming part, comprises an attracting member capable of being moved between an attracting position at which the attracting member attracts a sheet from within the cassette and a feeding position which lies above the attracting position, a pressing roller capable of being moved between a position of retraction and the feeding position, and a rotary roller capable of cooperating with the pressing roller in nipping the sheet at the feeding position. The pressing roller moves to the feeding position after the elapse of a prescribed time following the completion of the motion of the sheet by the attracting member to the feeding position. The rotary roller is rotatably set in place at the feeding position. The rotary roller may be attached to the attracting member in such a manner as to be moved vertically in both directions in conjunction with the attracting member. When the leading end of the sheet being conveyed by the attracting member from the attracting position to the feeding position comes into contact with the pressing roller held at the position of retraction, the pressing roller acts upon the sheet in the direction of returning the sheet to the cassette.
