Abstract

An image-forming method for fixing a toner image onto a recording medium,(i) wherein when a high-gloss recording medium (G0>40) is used, an image is formed at a low-speed mode process speed of from 20 mm/sec. to less than 130 mm/sec. and, where the maximum and minimum gloss values of the fixed image (Gmax1 and Gmin1, respectively), satisfy: Gmax1≦G0+40 and Gmin1≧G0−25; and(ii) wherein when a low-gloss recording medium (0≦G0≦40) is used, an image is formed at a high-speed mode process speed of from 130 mm/sec. to 600 mm/sec. and, where values of the fixed image (Gmax2 and Gmin2, respectively), satisfy: Gmax2≦G0+20 and Gmin2≧G0−15.
