The present invention has been made to provide an image forming apparatus capable of suppressing occurrence of a problem which is based on a sheet feeding speed with a simple configuration without increasing cost and changing a process speed. The image forming apparatus according to the present invention comprises: a drive controller 101 that controls the drive speed of an intermediate feeding roller 38 for feeding a sheet to a regist roller 37 for performing skew correction for the sheet; and a feeding speed information acquisition section 102 that acquires information relating the feeding speed of the sheet to be fed to the intermediate feeding roller 38. The drive controller 101 controls the drive of the intermediate feeding roller 38 with a feeding speed for duplex printing and a process speed based on the information relating to the feeding speed acquired by the feeding speed information acquisition section 102. The feeding speed for duplex printing is a speed at which a sheet to be resupplied to the intermediate feeding roller 38 for image forming onto the second surface thereof is received by the intermediate feeding roller 38 after the sheet has been passed through the regist roller 37 and a toner image has been formed onto the first surface thereof. The process speed is a speed at which a sheet is fed by both the intermediate feeding roller 38 and regist roller 37. The drive of intermediate feeding roller 38 is controlled such that the feeding speed for duplex printing becomes 1 to 1.3 times the process speed.
