摘要：
A toner is provided. The toner includes a resin and a fluorine-containing component. The toner satisfies the following formula: 5.0≤FXPS/FXRF≤25.0 where FXPS (atomic %) represents a content rate of fluorine atom in the toner determined by X-ray photoelectron spectroscopy (XPS) and FXRF (weight %) represents another content rate of fluorine atom in the toner determined by X-ray fluorescence analysis (XRF).
