Abstract:
A toner comprising a toner particle containing an amorphous polyester resin, a crystalline polyester resin and a wax, wherein in a cross-section of the toner by transmission electron microscopy (TEM), domains of the wax and crystals of the crystalline polyester resin are present, the area occupied by the domains of the wax is 0.5% to 8.0% and the area occupied by the crystals of the crystalline polyester resin is 0.5% to 8.0% of the cross-sectional area of the toner, the number-average diameter Dw of the domains of the wax is 60 nm to 240 nm, the aspect ratio of the crystals of the crystalline polyester resin is 5.0 to 25.0, and the number-average diameter Dc of major axis lengths of the crystals of the crystalline polyester resin is 0.8 to 2.0 times the Dw.
