1. An image forming method using at least four color toners of yellow, magenta, cyan and black, and comprising a fixation step of fixing a toner image on a recording medium using a fixing unit, wherein the total of a dust emission amount from each of the four color toners is less than 16 mg/h, and
when, of the yellow toner, the magenta toner and the cyan toner, just before the fixation step, a dust emission amount from the toner to be the outermost layer on the recording medium is represented by A (mg/h), a dust emission amount from the toner to be the interlayer on the recording medium is represented by B (mg/h), a dust emission amount from the toner to be the lowermost layer on the recording medium is represented by C (mg/h), A/C is from 1.5 to 23.7, and A, B and C each satisfy the relationship of 0.9≦A<14.2, 0.6≦B<14.2 and 0.6≦C<14.2. |
