<p>An object of the present invention is to provide the resin composition for electro-photographic toner, which the electro-photographic toner to be obtained by it is superior to low temperature fixing properties and a hot offset resistance, and the electro-photographic toner thereof. To be achieved this purpose, multi-branched state polyester structure having a structure representing the following structural formula (1) as a repeating unit, is made into a main skeleton (In the formula, R expresses an aliphatic hydrocarbon group, and n shows the number of repeating units of a branched structure and is an average of 1 - 5.) *a is a node of the carbon atom of a carbonyl group, *b is a node of an oxygen atom, and *b is bonded to *a in the other repeating unit of the structural formula (1)). In addition, polyester resin (A) having a ratio of 25 to 95 % of the weight for alkyl group of the number of carbon atoms 20 - 80 or alkenyl group of the number of carbon atoms 20 - 80 to the molecular terminal and aliphatic series crystalline polyester resin (B) is contained. The electro-photographic toner containing the resin composition for electro-photographic toner and this composition is provided.</p> |
