Claim:
1. An image processing device, comprising: a central processing unit (CPU) that: when thinning the image data whose resolution has been converted into the resolution higher than the resolution at a time of rasterization, the CPU makes a thinning strength larger than a thinning strength in a case of thinning the image data whose resolution has not been converted, the CPU detects an edge of an object forming a specific pattern in the image data before resolution conversion when converting the resolution of the image data higher than upon rasterization, and adds a pixel value to each of background pixels in the image data after resolution conversion; and the CPU makes the thinning strength larger when thinning the image data whose resolution has been converted higher than upon rasterization and to which the pixel value is added upon resolution conversion.
