The present disclosure provides a toner excellent in low-temperature fixability and excellent in durability under harsh environments of high-temperature and high-humidity, and a method for producing the toner. The toner can contain: a toner particle containing a binder resin, wax, and an inorganic oxide particle; and an external additive, wherein the inorganic oxide particle contains, as a main component, an oxide of at least one element selected from the group consisting of Si, Mg, Al, Ti, and Sr; when a thin piece obtained by cutting the toner with a microtome is observed with a transmission electron microscope (TEM), the major axis A of the inorganic oxide particle is 0.10 to 3.00 μm; and in a wettability test of the toner with respect to a methanol/water mixed solvent, a methanol concentration at a transmittance of light having a wavelength of 780 nm of 50% is 5.0 to 30.0% by volume.
A toner comprising:
A method for producing a toner, the toner comprising a toner particle containing a binder resin, wax, and an inorganic oxide particle, and an external additive, the method comprising:
