Abstract

PURPOSE:To erase periodical unevenness of movement of a photosensitive drum surface due to vibration, and to prevent deterioration of image quality, by changing print timing when mechanical vibration occurs. CONSTITUTION:An electrometer 51 detects surface potential of the photosensitive drum 31 which, when not used for image forming, is to be uniformly charged, and a high speed Fourier transformation calculator 59 computes its variation frequency, and printing information in a page memory 11 is recomposed on the basis of this result. Since the timing at which the printing information is read out is displaced so as to erase unevenness of drum surface movement, the image obtained is freed of unevenness.
