置の給紙装置。[Scope of Claim for Utility Model Registration] A paper storage device such as a paper feed cassette, a bottom plate that urges the paper upward inside the paper storage device, and a snubber provided at the tip of the paper feed section. In a paper feeding device including a paper handling mechanism and a half-moon roller serving as a paper feeding roller for feeding out sheets of paper stored in the paper storage device one by one, the tip portion of the paper feeding side of the paper storage device. A ski member is provided for pressing the paper feed roller, the ski member is provided to be swingable relative to the support shaft via a support arm means, a cam device is provided coaxially with the paper feed roller, and the cam device is configured to press the paper feed roller. The roller is arranged so that it rotates at a position slightly higher than the contact position with the paper, and the paper is pressed by a pressing means via a cam device just before the paper feed roller rotates and comes into contact with the paper. A paper feeding device for an image forming apparatus, characterized in that the paper feeder is configured to be able to feed the paper using a half-moon roller while maintaining the height of the paper constant.
