TONER FOR IMAGE FORMATION, DEVELOPER FOR IMAGE FORMATION AND IMAGE FORMING METHOD

PROBLEM TO BE SOLVED: To provide a toner for image formation adaptable to a low temperature fixing system even on transfer paper having a rough surface, excellent in smear resistance and capable of achieving high image quality. SOLUTION: The toner for image formation is used in an image forming method in which the toner is fixed on a transfer material by heat and pressure and the transfer material has a smoothness of ≤40 s. The toner includes at least a binder resin and a colorant, (i) the toner is fixed at a temperature at which a storage modulus G' is in the range of 0.3×104-1.0×104Pa and a loss modulus G" is in the range of 0.2×104-0.7×104Pa, (ii) tanδ(=G"/G') has a maximum value in the range of 90-110°C and the value is in the range of 1.2-1.7, and (iii) a storage modulus G'(180) at 180°C is ≥0.2×104.
