Abstract
Magnification correction of an image is performed by changing the cycle time of an optional pixel in the unit of pixel, until a phase adjustment amount (phase shift value) calculated by fixing the frequency exceeds a preset specified value, and after the phase adjustment amount exceeds the preset specified value, magnification correction of the image is performed by changing the frequency of an image signal in the unit of a line or in the unit of a plurality of lines. Accordingly, the number of execution of the magnification correction of an image by the latter method, in which it is necessary to suspend the image forming operation at the time of execution thereof, can be reduced.
