摘要：
A toner including a binder resin and a colorant, the toner having a core-shell structure containing a core and a shell, wherein the binder resin contains a crystalline polyester resin and a non-crystalline polyester resin, wherein a ratio (A/B) of a mass (A) of the crystalline polyester resin to a mass (B) of the non-crystalline polyester resin is 5/95 to 75/25, and wherein a ratio (Ds/Dc) of a hardness (Ds) of the shell to hardness (Dc) of the core is 1.05 to 1.50 where the hardnesses (Ds) and (Dc) are measured with a scanning probe microscope.
