To provide an image forming apparatus and a double-sided printing method for the image forming apparatus that can prevent occurrence of an image failure by providing a sheet retracting mechanism in a conveying path of an automatic double-sided printing device and preventing occurrence of temporary stop near a high-temperature fixing device during a double-sided printing operation. The image forming apparatus includes an image forming unit 1A that forms images on sheets E and F, a fixing device 17 that fixes the images formed by the image forming unit 1A on the sheets E and F, an automatic double-sided printing device 81 that has a conveying path 82 for conveying the sheets E and F having the images fixed thereon by the fixing device 17 into the automatic double-sided printing device 81 and reversing the sheets E and F conveyed into the automatic double-sided printing device 81 to feed the sheets E and F to the image forming unit 1A, and a retracting mechanism 106 that stops the sheets E and F, which is stopped to be conveyed in the conveying path 82, in a position away from the fixing device 17 to retract the sheets E and F from heat of the fixing device 17, the retracting mechanism 106 being provided in the conveying path 82 of the automatic double-sided printing device 81.
