In a toner containing at least a binder resin, a colorant, an ester compound and a low-melting material, the ester compound is an ester of dipentaerythritol with a carboxylic acid having 18 or more to 25 or less carbon atoms, and, where the melting point of the ester compound is represented by Tm(A)(° C.) and the melting point of the low-melting material is represented by Tm(B)(° C.), the toner satisfies the relationship of:in-line-formulae description="In-line Formulae" end="lead"?Tm(B)≦Tm(A)+5.in-line-formulae description="In-line Formulae" end="tail"?
