<P>PROBLEM TO BE SOLVED: To provide a document feeder which can efficiently clean the surrounding air of an image forming apparatus body by maintaining the ion generating efficiency of an ion generator to be high. <P>SOLUTION: The document feeder includes a document load tray, ducts 221 to 223, a ventilating section 227, and an ion generating device 229. The document load tray 220 is a member for loading thereon a document to be read and has holes 201 to 203 and holes 211 to 213 extending therethrough to provide communication between a document load side and a reverse side of the document load tray. The ducts 221 to 223 are placed on the document load tray continuously with the hole 225, etc., on a reverse side of the document load tray. The ventilating section 227 is configured to feed air present outside the image forming apparatus through openings 225, etc., of the ducts 221 to 223. The ion generating device 229 is disposed within the ducts 221 to 223 and configured to generate ions for cleaning up the air fed into the ducts 221 to 223 by the ventilating section 227. <P>COPYRIGHT: (C)2011,JPO&INPIT |
