Each of the toners has a softening point of from 125° C. to 135° C. The following relationships are satisfied: Ts(A)<Ts(B), Ay+5≦Am≦Ay+15, and Ac+5≦Am≦Ac+15, wherein Ts(A) and Ts(B) (° C.) each represent softening points of the resin (A) and (B), respectively, and Ay, Am, and Ac each represent ratios (% by weight) of the amount of the resin (A) to total amount of the resins (A) and (B) in the yellow, magenta, cyan toners, respectively.
