ABSTRACT:
This invention provides an image printing method and apparatus which accurately correct the read timing of a sensor system used to correct the position of a toner image in the correction operation mode, and accurately corrects the magnification of an image in the vertical direction in the print operation mode. An image printing apparatus according to the invention includes an image printing unit which prints a toner image on an intermediate transfer belt, and a control unit which controls the rotational speed of the intermediate transfer belt by detecting a toner image printing on the intermediate transfer belt by the image printing unit. When the correction operation mode is selected, the control unit executes feedback control on the rotational speed of the intermediate transfer belt on the basis of vertical magnification adjustment value data. When the print operation mode is selected, the control unit executes feedback control on the rotational speed of the intermediate transfer belt on the basis of vertical magnification adjustment value.
