ABSTRACT:
An image forming apparatus includes plurality image carriers sequentially arranged, a conveying belt, which conveys a print medium onto which color-separated images formed on the plurality of image carriers are overlapped, and a plurality of image transfer rollers installed to respectively correspond to the plurality image carriers. The conveying belt is interposed between the image transfer rollers and the image carriers. At least one of the plurality image transfer rollers is arranged to be compressed with a pressure higher than those applied to the other image transfer rollers against the image carriers.
