Toner having excellent low-temperature fixability and heat-resistant storage stability and durability capable of withstanding stress such as stirring in a developing machine, and developer, image forming apparatus, and image forming method using the toner Provided. A toner having a core-shell structure including at least a binder resin and a colorant and including a core and a shell, wherein the binder resin includes a crystalline polyester resin and an amorphous polyester resin. And the mass ratio (A / B) of the crystalline polyester resin (A) to the amorphous polyester resin (B) is 5/95 to 75/25, and the core was measured with a scanning probe microscope. The toner has a ratio (Ds / Dc) of 1.05 to 1.50 between the hardness (Dc) of the toner and the hardness (Ds) of the shell. [Selection] Figure 2 |
