Abstract
An image forming apparatus and a control method enhancing ACR (Auto Color Registration) performance by optimizing ACR patterns are provided. The apparatus includes a photosensitive drum, an exposure unit to radiate the drum to form an latent image, a developing unit supplying color toner corresponding to the latent image, and a transfer belt to which the toner image is transferred. A pattern generating unit forms a latent image corresponding to a predetermined ACR pattern on the drum to form the ACR pattern on the transfer belt, and allowing amounts of gap changes of sub patterns, which form the ACR pattern, to have an average value of about 0, the gap change of sub patterns caused by an AC component generated from a rotation of the drum. A pattern detecting unit detects a pattern formed on the transfer belt, and an ACR executing unit calculates offsets to correct errors.
