Abstract: An image forming apparatus and method which reduces time taken for color registration and reflects misregistration of colors in real time to correct color misregistration of prints are provided. Image forming apparatus may include photoconductor elements corresponding to colors; first sensing unit arranged between first and second photoconductor elements among photoconductor elements, and sensing toner images transferred to intermediate transfer body; final sensing unit arranged after final photoconductor element among photoconductor elements, and sensing transferred toner images; and controller calculating fixed errors of remaining colors except for first color among colors, with respect to first color corresponding to first photoconductor element, based on output values of final sensing unit before printing, calculating variable error based on output value of first sensing unit during printing, and adjusting scanning time of at least one color of remaining colors in real time in consideration of fixed errors and variable error.
