Image forming apparatus and sheet feeding method

摘要

The present invention has been made to provide an image forming apparatus, a sheet feeding method, and a sheet feeding program capable of eliminating the problem that the leading end of a sheet hits against the bottom portion of a reverse feeding path and contributing to an increase in sheet feeding efficiency without adding special parts and preventing the miniaturization of the entire apparatus. An image forming apparatus comprises a drive control section 101 that controls drive of feeding rollers that guide a sheet to a reverse feeding path and then feed the sheet in a switchback manner; and a sheet information acquisition section 102 that acquires information relating to the sheet size in the feeding direction of a sheet to be switched back. The drive control section 101 controls drive of the feeding rollers in such a manner as to make the introduction speed of only the sheet having a predetermined size into the reverse feeding path lower than the introduction speed of other sheets having a size smaller than the predetermined size based on the information relating to the sheet size in the feeding direction thereof that the sheet information acquisition section 102 has acquired.
