ABSTRACT:
An image recording apparatus includes a rotationally driven image carrier; a position signal output device for outputting a position signal indicating that the image carrier is at a predetermined rotational position; a scanning device for scanning a photosensitive drum with a light beam which is modulated in accordance with the image signal; a beam detection signal generating device for generating a beam detection signal upon detection of the light beam at a predetermined position, so as to regulate the timing of the light beam modulation by the image signal for each line of scan; an image transferring/superposing device for successively transferring and superposing on the image carrier a plurality of color image components which are successively formed on the photosensitive drum based on the image signals which are input in response to the position signals for formation of respective color image components; a measuring device for measuring the time difference between the position signal and the detection signal for each color image component, and a control device for controlling at least the rotation of the image carrier based on the time difference measured by the measuring device.
