An automatic document feeder with an anti-skew function is disclosed. The automatic document feeder comprises a pick up roller for feeding documents loaded on a tray, a feed roller for transferring the fed documents toward document scanning means; and an intermediate roller disposed just before the feed roller to transfer the documents toward the feed roller. The Intermediate roller has a document feed speed on a surface thereof faster than that of the feed roller. It is possible to prevent skew from occurring between the REGI roller or the intermediate roller and the feed roller by merely adjusting a linear velocity of the REGI roller or the intermediate roller, thereby improving document feeding performance and extending a lifetime of the device such as a motor since a driving system has no additional load.
