特徴とする給紙装置。[Scope of Claim for Utility Model Registration] A paper feed cassette that is removably installed in the main body of an image forming apparatus, and a paper feed roller that feeds the paper by coming into contact with the uppermost sheet stacked in the paper feed cassette. In the paper feeding device, the paper feeding roller moves downward as the uppermost paper surface descends after the paper is fed, and the paper feeding roller moves downward to follow the lowering of the uppermost paper surface of the paper feeding cassette, which faces in the conveyance direction of the paper conveyed by the paper feeding roller. The side plate is formed into a curved surface having a shape substantially corresponding to a locus of movement of the circumferential surface of the paper feed roller so that the circumferential surface of the paper feed roller moves along the inner surface of the side plate,
A paper feeding device characterized in that the paper feeding roller cooperates with an inner surface of the side plate to separate and feed the uppermost sheet of the paper feeding cassette.
