An image alignment method and an image forming apparatus employing the same are provided. The apparatus includes a test mark detector for detecting first and second test marks printed on a printing medium, an encoder output pulse generator for generating encoder output pulses, an absolute position determiner for determining absolute positions by counting the encoder output pulses output from the encoder output pulse generator, and an actual distance calculator for receiving first and second position values output from the absolute position determiner when the first and second test marks are detected and for calculating an actual distance between the first and second test marks using the first and second position values.
