摘要： Disclosed is an image forming apparatus, which makes it possible to appropriately conduct a controlling operation for eliminating the velocity fluctuation of the photoreceptor drum without generating any malfunction. The apparatus includes a photoreceptor member driven by a motor and a control section that is provided with a feed forward controlling section that stores parameters derived from driving errors for one revolution of the photoreceptor member to create a reverse-phase instruction value based on the parameters and a feedback controlling section that controls a velocity of the photoreceptor member, so as to keep the velocity of the photoreceptor member constant. During an initial operating time, the control section deactivates the feed forward controlling section, while only activates the feedback controlling section to drive the photoreceptor member so as to measure a driving toque of the driving motor, and selects a parameter from the parameters, corresponding to the driving toque measured.

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.
