Claim:
1. 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 from 0.5% to 8.0% and the area occupied by the crystals of the crystalline polyester resin is from 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 from 60 nm to 240 nm, the aspect ratio of the crystals of the crystalline polyester resin is from 5.0 to 25.0, and the number-average diameter (Dc) of major axis lengths of the crystals of the crystalline polyester resin is from 0.8 to 2.0 times the number-average diameter (Dw) of the domains of the wax.
