ABSTRACT:
In an image forming apparatus, when images are formed on a sheet on and after a second round of an image forming operation, an image forming pitch by a print head which linearly forms the images in the direction perpendicular to the image forming line is controlled so as to vary from the preceding pitch corresponding to the rate of expansion and contraction of the sheet in the preceding image forming operation. When images are formed on a sheet on and after the second round of the image forming operation, the length of the image to be formed is controlled for expansion and contraction corresponding to the actual rate of expansion and contraction automatically detected by a size detecting sensor in the preceding image forming operation.
