<p>Provided is a toner that fixes well at low temperatures and makes it possible to obtain high image density without blurring even with long-term use. The toner contains, at least, a binding resin, a colorant, an ester compound, and a low-melting-point substance. The ester compound is characterized by comprising dipentaerythritol and a carboxylic acid with a carbon number between 18 and 25, inclusive, and is further characterized in that the melting point Tm (A) of the ester compound and the melting point Tm (B) of the low-melting-point substance, in degrees Celsius, fulfill the relation Tm (B) = Tm (A) + 5.</p> |
