PROBLEM TO BE SOLVED: To provide a toner which has excellent low-temperature fixability and blocking resistance, has excellent dispersibility of an internal additive and does not give rise to the contamination of developing/fixing members even in long-term duration. SOLUTION: The toner is prepared by using at least two resins containing polyester units for a binder resin. The two resins have specific storage moduli of elasticity at 50°C and 100°C and are controlled in the ratio of the respective storage moduli of elasticity at 50°C and 60°C so as to satisfy a specific range and conditions.
