摘要： An apparatus for forming an image corresponding to an input image signal, includes a light beam generator for generating a light beam; a driver for driving the light beam generator; and an image outputting device for scanning the generated light beam which has been reflected by a rotary polygonal mirror to a recording medium in a primary direction and, for moving the recording medium in a secondary direction substantially perpendicular to the primary direction so that the image is formed. A periodical modulation signal generator changes a phase or an amplitude of a first reference signal including a fundamental frequency having a period corresponding to one rotation of the rotary polygonal mirror, and generates a plurality of periodical modulation signals having different phases or different amplitudes from each other. A multiplier multiplies a second reference signal having a predetermined frequency value by the plurality of periodical modulation signals respectively. A controller controls the driver and the image outputting device in accordance with a plurality of multiplied periodical signals, and forms images respectively corresponding to the plurality of multiplied periodical signals. A periodical modulation signal inputting device inputs a first periodical modulation signal corresponding to a first position on the recording medium, and a second periodical modulation signal corresponding to a second position different from the first position. A calculator generates an unevenness correction signal in response to the inputted first and second periodical modulation signals.
