紙送り装置。[Scope of Claim for Utility Model Registration] (1) In a paper feeding device that feeds documents one by one to an image forming device, the leading edge of the document hits a specific roller that is in a stopped state on the conveyance path leading to the image forming device. At the same time, the rear portion of the document continues to advance until the document is in a curved state, and then stops, and then the specific roller is reversed for a predetermined period of time, and the surface of the specific roller is cleaned with the leading edge of the document. A paper feeding device characterized in that it is provided with a control means for controlling the paper feeding device. (2) The specific roller is disposed between a separation unit that separates the original into one sheet and a conveyance unit that transports the original onto the platen of the image forming apparatus, and temporarily contacts the leading edge of the original. 2. The paper feeding device according to claim 1, wherein the paper feeding device is a registration roller that draws a registration loop to measure the posture correction and also measures the timing of feeding to the conveying section. (3) The paper feeding device according to claim 1, wherein the specific roller is a first roller on the document entrance side of a conveying section configured by arranging a plurality of rollers on a platen of the image forming apparatus.
