摘要： A method and apparatus are provided for compensating for the degradation of a print image due to a malfunctioning nozzle that irregularly ejects ink. A malfunctioning nozzle is detected among nozzles installed in an inkjet image forming apparatus, and image data of a print position adjacent to a compensation position printed by the malfunctioning nozzle is exchanged for image data of a print position in an interest or inspection region near the compensation position. Accordingly, degradation of print quality, such as, for example, an unintended visible white band, can be prevented and the lifetime of the printhead can be lengthened.
