摘要：
A toner is provided including a colorant; a resin composition (A) comprising at least one binder resin and a hydrocarbon wax having a melting point of 70-90° C. in an amount of from 6 to 30% by weight based on total weight of resin composition (A), and having a softening point (T1/2(A)) of from 120 to 150° C.; and a resin composition (B) having a softening point (T1/2 (B)) of from 100 to 130° C., wherein a weight ratio of the resin composition (A) to the resin composition (B) is from 10/90 to 45/55, and the following relationship is satisfied: T1/2(A)≧T1/2(B)+3; and the use of the toner in an image forming method, an image forming apparatus, and a process cartridge.
