摘要： There is described a duplex image-forming apparatus having a function of forming images onto both sides of a transfer material. The apparatus includes an image-forming section to respectively form an obverse-side image and a reverse-side image on a photoreceptor element by scanning a light beam, modulated with image signals based on pixel-clock signals and reflected from a polygon mirror rotating at an operating velocity based on polygon-clock signals; a transferring section to transfer said obverse-side image and said reverse-side image onto both surfaces of said recording sheet; a fixing section to fix the images onto both surfaces of said recording sheet; and a clock-frequency changing section to change a pixel-clock frequency, and a polygon-clock frequency, corresponding to a degree of shrinkage of said recording sheet caused by a fixing operation performed in said fixing section, at a transition time of an image-forming operation from one side to another side.

摘要： There is provided a controller that controls and drives the polygon mirror to a target speed with keeping a predetermined phase. When the controller controls the speed of the polygon mirror along with the image magnification adjustment, the controller controls the polygon mirror with a waiting time t1 from an end of the speed control of the polygon mirror for stabilizing before the phase control and a waiting time t2 from an end of the phase control of the polygon mirror for stabilizing, the t1 and t2 being set with a relation of t1
