Abstract
An image forming apparatus and an auto color registration method thereof. The automatic color registration method of the image forming apparatus, the method includes transferring a plurality of first patterns synchronized with a phase of an image receptor, detecting the transferred first patterns, and performing an automatic color registration (ACR) by controlling a driving speed of the image receptor based on the detected first pattern. With this, the apparatus and method controls a driving speed of an image receptor by using a pattern synchronized with a phase of the image receptor and improves accuracy of the ACR.
