It is determined whether the pixel of interest in image data to be processed belongs to areanot close to a scan line changing point where a scan line changing process is done (S). If the pixel of interest belongs to area, an error diffusion process is performed using an error diffusion matrix for area(S). If the pixel of interest belongs to areaclose to the scan line changing point, the error diffusion process is performing using an error diffusion matrix for downward scan line changing for areawhen the scan line changing process is changing to a lower line, or an error diffusion matrix for upward scan line changing for areawhen the scan line changing process is changing to an upper line.
