    摘要： The toner includes a binder resin; a colorant; and a release agent. The first inter-particle force Fp(A) of the toner, which is measured under an environmental condition of 23° C. and 60% RH after the toner is pressed for 1 minute at 25° C. under a compression stress of 15 kg/cm2, is from 1.0×10−9 (N) to 1.0×10−6 (N). The difference (Fp(B)−Fp(A)) between the second inter-particle force Fp(B) of the toner, which is measured under the environmental condition of 23° C. and 60% RH after the toner is pressed for 1 minute at 50° C. under a compression stress of 15 kg/cm2, and the first inter-particle force Fp(A) is 0 (N) to 1.0×10−7 (N).
