Provided is a toner that improves transferability more than ever. A toner including toner particles having a surface layer containing an organosilicon polymer, wherein the organosilicon polymer has a specific partial structure, and in X-ray photoelectron spectroscopic analysis, silicon on the surface of the toner particles. In the roughness curve measured with a scanning probe microscope of the toner particles, the arithmetic average roughness Ra (nm) is 10 nm or more and 300 nm or less in the atomic concentration dSi of 1.0 atom% or more and 22.2 atom% or less. Yes, when the standard deviation of Ra is σRa (nm), σRa / Ra is 0.60 or less, and the average length RSm (nm) of the toner particle roughness curve element is 20 nm or more and 500 nm in the roughness curve. A toner characterized in that σRSm / RSm is 0.60 or less, where σRSm (nm) is the standard deviation of RSm. [Selection figure] None |
