An inkjet image forming apparatus and method of compensating for a defective nozzle in an inkjet image forming apparatus are provided. By analyzing firing states of nozzles firing ink at a compensated position, which is a position printed with the defective nozzle, and at positions adjacent to the compensated position, and by firing ink having a color different from that of the defective nozzle at the compensated position according to the firing states of the nozzles to diffuse the ink fired at the adjacent positions into the compensated position, the defective nozzle is compensated. Accordingly, the missing dot of the defective nozzle is compensated for, so that it is possible to prevent deterioration in image quality such as a white band which can be easily perceived by a user. In addition, by adjusting a firing amount or chroma of the ink fired at the compensated position or the adjacent positions, it is possible to improve a compensation effect.
