Image forming apparatus having scan position correction
 An image forming apparatus includes an exposing unit for performing exposure by scanning a beam to a photosensitive belt to form an electrostatic latent image, a developing unit for forming a toner image by supplying liquid toner to the electrostatic latent image formed by the exposing unit, a sensor for detecting the position of the toner image formed on the photosensitive belt, and a controller for calculating a positional error by comparing the position detected by the sensor with an established reference position and controlling exposure performed by the exposing unit to correct the calculated positional error. Thus, since errors between the established scanning position and the actual scanning position are automatically corrected during scanning, the scanning can be performed more precisely and conveniently.
