PROBLEM TO BE SOLVED: To provide a toner that is excellent in all of the low-temperature fixing properties, anti-offset property, storage stability, mechanical strength, anti-fouling property to developing devices, toner filming resistance to latent electrostatic image bearing members and carrier particles and pulverizability and is capable of forming high-quality images over a long period of time. SOLUTION: The present invention provides a toner containing at least a binder resin, a releasing agent, and a colorant, wherein the binder resin contains at least a polyester resin (A) having a softening point tm (A) of 120°C to 160°C, a polyester resin (B) having a softening point Tm(B) of 80°C or more and less than 120°C and a composite resin (C) containing a condensation polymerization monomer and an addition polymerization monomer, at least any one of the polyester resin (A) and (B) is a polyester resin prepared by condensation-polymerizing an alcohol component substantially composed of only aliphatic alcohol with a carboxylic acid component, and 65 mol% or more of the alcohol component is 1.2-propanediol.
