发明名称 Image forming apparatus, image forming method, and computer program product
摘要 An image forming apparatus includes a first density correction unit that corrects density correction characteristics in correcting density of print image data to be output by using a density correction patch formed in an image forming process; a second density correction unit that corrects the density correction characteristics by using a density correction patch printed on a recording sheet; an image inspection unit that compares an image density of inspection image data obtained by scanning a printed output image with an image density of the print image data to be output, thereby inspecting a magnitude of a density change in the printed output image; and a density control unit that selects one from the first and second density correction units according to the magnitude of the density change and causes the density correction characteristics to be corrected by the selected one from the first and second density correction units.
