Abstract:
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: Tm(B)≦Tm(A)+5.
