PROBLEM TO BE SOLVED: To write with a magnification corrected according to set information on transfer papers to be used and obtain images with less error in magnification by providing the information on the transfer papers to be used to an image- forming apparatus. SOLUTION: When information on transfer papers to be used is provided from paper kind information 1, the image-forming apparatus writes according to main and sub write correct values determined beforehand by an initial state of the transfer papers and an amount of extension/shrinkage of the papers after transferred. For example, when a transfer paper (a) is a size A3 and delivered in a longitudinal direction, and if the transfer paper (a) (having a breadthwise direction as a main scanning direction and the longitudinal direction as a sub scanning direction) is known to extend by approximately 0.5% in the breadthwise direction and shrink by approximately 0.4% in the longitudinal direction after delivered in comparison with before delivered, images are formed by using the correct values corresponding to the amount of expansion/shrinkage.
