In an image-forming method having a fixing step of fixing a toner image onto a recording medium, and having at least a low-speed mode and a high-speed mode so as to be able to form images at different speeds; n the recording medium has a gloss value (60-degree gloss) represented by Go and the toner is laid on the recording medium in a quantity ranging from 0.05 mg/cm 2 to 1.3 mg/cm 2 , under conditions of which; n (i) when a recording medium having a high gloss (G 0 >40) is used, an image is formed at a low-speed mode having a process speed of from 20 mm/sec. to less than 130 mm/sec. and, where the maximum value and minimum value of gloss value of the fixed image are represented by G max1 and G min1 , respectively, they satisfy: G max1 ≦G 0 +40 and G min1 ≧G 0 −25; and n (ii) when a recording medium having a low gloss (0≦G 0 ≦40) is used, an image is formed at a high-speed mode having a process speed of from 130 mm/sec. to 600 mm/sec. and, where the maximum value and minimum value of gloss value of the fixed image are represented by G max2 and G min2 , respectively, they satisfy: G max2 ≦G 0 +20 and G min2 ≧G 0 −15. |
