An ink-jet image forming apparatus and method for compensating for a defective nozzle are provided. The ink-jet image forming apparatus includes a recording medium transferring unit to transfer a recording medium in a first direction, a printhead to extend substantially parallel with a second direction, the second direction transversing the first direction, on which a nozzle unit is defined, the nozzle unit having nozzles through which ink droplets are ejected onto the recording medium, a carriage with the printhead mounted thereon, a carriage transferring unit to reciprocate the carriage in the second direction, and a controller to synchronize operations of the recording medium transferring unit, the printhead, and the carriage transferring unit, and to print the ink droplets ejected by the nozzles in a desired position of the recording medium so as to disperse an effect of a defective nozzle. The method includes: receiving a printing environment, detecting the defective nozzle in the nozzle unit by a detecting unit, and reciprocating the printhead in a longitudinal direction to disperse an effect of the defective nozzle.
