摘要： PROBLEM TO BE SOLVED: To adjust image sizes on the front and back with higher accuracy than heretofore, without dropping printing productivity as much as possible. SOLUTION: In addition to a driving section that drives a rotary polygon mirror in response to a supplied clock signal, the image forming apparatus includes a frequency adjustment section, a phase difference determining section, and a switching control section. In order to reduce a difference between the magnification of an image formed on a first side of a recording medium and the magnification of an image formed on a second side of the recording medium, the frequency adjusting section adjusts, according to the contraction of the recording medium that has the image formed on the first side, the frequency of the clock signal supplied to the driving section when the image is formed on the second side. According to the frequency difference between the clock signal corresponding to the first side and the clock signal corresponding to the second side and the sign of the difference, the phase difference determining section determines the phase difference between the clock signal corresponding to the first side and the clock signal corresponding to the second side. The switching control section switches from the clock signal corresponding to the first side to that corresponding to the second side so that the determined phase difference is obtained.

摘要： It is an object of the invention to correct a tilt of an image inputted in a tilted state for a sentence of an original without intervening the operation of the user. For this purpose, projections of two partial images are obtained at check points which were properly decided in the input image information. A tilt angle of an original is obtained from a correlation position of the projections of each partial area. By dividing the image into belt-shaped small areas and shifting in accordance with the tilt angle obtained, an image in which the tilt of the input tilted image was corrected is formed.
