Abstract: An image forming apparatus includes an image forming unit which transfers an image obtained through exposure and development to paper, and a control unit which changes a rotation speed of a polygon mirror at an intermediate area on a carrier to change a reduction/magnification ratio of an image. The control unit changes the rotation speed in a stepwise manner in such a way as to allow a stable rotation of the polygon mirror in each step, and controls the image forming unit to form a corrected patch image in parallel with the stepwise change of the rotation speed. The corrected patch image is obtained through correction in accordance with the stepwise change of the rotation speed to be the same as the patch image formed when the rotation speed is not changed.

Abstract: There is described an image forming apparatus, which makes it possible to easily create a booklet sample. The apparatus includes: a determining section to determine whether or not instruction information for instructing the apparatus to create a booklet sample is attached to print data; and a controlling section to control the image forming apparatus to create the booklet sample in which at least a part of inner pages is printed in a predetermined mode. The predetermined mode includes any one of: a first mode in which all of the inner pages other than the front and the back cover sheets are made to be white papers; a second mode in which only the front and back cover sheets and specific inner pages are to be printed; and a third mode in which only the front and back cover sheets and initial pages of chapters are to be printed.
