Abstract
A method of controlling performance of auto color registration (ACR) of a color image forming apparatus, and an image forming apparatus using the same are provided. The method of controlling performance of ACR includes forming a composite black image on a transfer belt, sensing the composite black image by using a sensor, measuring the sensed composite black image, and performing ACR correction when a measured width of the composite black image is greater than a previously set value. Accordingly, it is possible to prevent unnecessary performance of ACR control when no color misregistration has occurred. In this way, ACR control is performed in as short a time as possible so that performance of the image forming apparatus may be improved. Also, it is possible to prevent waste of ACR performance time and life span reduction of a driving source for ACR.
