More Information
Summary:Provided is a toner including a binder resin, a colorant, a crystalline polyester, and a release agent, wherein a cross-sectional image of the toner is observed using a scanning transmission electron microscope, domains of the crystalline polyester are present in the cross-sectional image of the toner, the domains have a number-average major diameter of at least 50 nm and not more than 300 nm, the number of the domains is at least 8 and not more than 500, and the domains are present at at least 60 number % and not more than 100 number % from an outline of the cross-sectional image to 25% of the distance between the outline and the centroid of the cross-sectional image. 提供了种调色剂，其包括粘结剂树脂、着色剂、结晶性聚酯和脱模剂，其中使用扫描透射电子显微镜来观察所述调色剂的截面图像，所述结晶性聚酯的域存在于所述调色剂的截面图像中，所述域的数均长径为50nm以上且300nm以下，所述域的个数为8个以上且500个以下，并且所述域在从所述截面图像的轮廓至所述轮廓与所述截面图像的重心之间的距离的25％内存在60个数％以上且100个数％以下。
