徴とする前記第１項記載の紙送り装置。[Scope of Claim for Utility Model Registration] (1) A paper feeding device that presses a collar provided concentrically with a guide roller to an image carrier to form a gap between the image carrier and the guide roller, and feeds paper through this gap. In the paper feeding device, the guide roller is configured to be deformable so as to adjust the relative positional relationship with the image carrier according to the thickness, rigidity, and other properties of the paper that has entered the gap. . (2) The guide roller is formed to have a diameter that can maintain the gap at a predetermined value when feeding thin sheets of paper, and is also formed to be able to bend in a direction to widen the gap when feeding thicker sheets. The paper feeding device according to item 1 above. (3) The guide roller is formed from a highly rigid roller and a soft rubber portion covered with the roller, and the soft rubber portion is configured to deform in a direction that widens the gap depending on the properties of the paper being fed. The paper feeding device according to item 1, characterized in that the paper feeding device is configured as follows.
