（１）該ポリエステル樹脂Ａは、結晶構造をとりうる部位を有する樹脂であり、
（２）該ポリエステル樹脂Ｂは、結晶構造をとりうる部位を有さない樹脂であり、
（３）透過型電子顕微鏡（ＴＥＭ）を用いた該トナーの断面観察において、該トナーの断面に該ポリエステル樹脂Ａ由来のドメインを有し、該ドメインの中で長径が最大のドメインの長径が３．０μｍ以上であり、
（４）該ドメインのアスペクト比（長径／短径）の平均が４．０以上２０．０以下であり、
（５）該ポリエステル樹脂Ａの融点Ｔａと該ポリエステル樹脂Ｂの軟化点Ｔｂが下記式１を満足することを特徴とするトナーを提供する。
Ｔａ＜Ｔｂ ・・・式１
The present invention relates to a toner containing polyester resin A, polyester resin B, and a colorant.
(1) The polyester resin A is a resin having a portion capable of taking a crystal structure,
(2) The polyester resin B is a resin that does not have a portion capable of taking a crystal structure,
(3) In the transmission electron microscope (TEM) cross-section observation of the toner with, the cross-section of the toner has a domain from the polyester resin A, the major diameter of the largest domain diameter in the domain Is 3.0 μm or more,
(4) The average aspect ratio (major axis / minor axis) of the domain is 4.0 or more and 20.0 or less,
(5) A toner is provided in which the melting point Ta of the polyester resin A and the softening point Tb of the polyester resin B satisfy the following formula 1.
Ta <Tb Formula 1
なお、本発明におけるポリエステル樹脂Ａドメインの最大長径及び平均アスペクト比は、透過型電子顕微鏡（ＴＥＭ）を用いたトナーの断面観察を行うことにより測定することができる。測定方法は限定されるものではなく、ポリエステル樹脂Ａのドメインの断面観察ができればよい。
The maximum diameter and average aspect ratio of the polyester resin A domain in the present invention can be determined by performing cross section observation of the toner using a transmission electron microscope (TEM). The measuring method is not limited, and it is only necessary to observe the cross section of the domain of the polyester resin A.
