ABSTRACT:
In an image forming apparatus, an image forming condition is changed depending on whether or not a recording material on which a toner image is formed is ordinary high gloss paper or thermoplastic resin coated paper. More specifically, in the case where a high gloss mode is selected during image formation, judgement whether or not the high gloss paper is the ordinary high gloss paper or the thermoplastic resin coated paper is made. In the former case, a screen line number is set to 150 lpi, and in the latter case, the screen line number is set to 200 lpi. As a result, image failure due to collapse of a toner layer (during fixation) on the ordinary high gloss paper is prevented and high-quality toner image is formed on the thermoplastic resin coated paper.
