<P>PROBLEM TO BE SOLVED: To provide an automatic document feeder that can read a non-warped image by controlling the release and restoration of a separation function of a separation means in proper timing, thereby keeping intervals between paper constant, maintaining high productivity, reducing a cause for a document skew and improving stability in feeding a document, and to provide an image forming apparatus. <P>SOLUTION: A reverse roller 10 moves between a separation position that comes into press-contact with a feed roller 9 and a separation releasing position that is separated from the feed roller 9 by an arm 10a and a cam member 10q. The reverse roller 10 is moved to the separation releasing position after an end of the document passes by the a separation part 401, and the reverse roller 10 is returned to the separation position before the next document is fed to the separation part 401. <P>COPYRIGHT: (C)2012,JPO&INPIT |
