PROBLEM TO BE SOLVED: To prevent reduction in throughput while preventing the deterioration of positional accuracy of image by solving the problem in which occurrence of skew during carrying of a sheet having image formed thereon deteriorates the positional accuracy when forming image on the sheet again. SOLUTION: A double-faced carrying roller 50 capable of performing skew correction is provided in a double-faced carrying path for carrying the sheet having image formed thereon to an image forming part again. Operation of skew correction by the double-faced carrying roller 50 is selectively executed based on a printing ratio or a difference between right and left printing ratios.
