In a toner comprising toner particles whichncomprise toner base particles containing at least anbinder resin and a magnetic material, and inorganicnfine particles, the toner base particles have beennobtained through a pulverization step; and, the tonernbase particles having a circle-equivalent diameter ofnfrom 3 µm or more to 400 µm or less as measured withna flow type particle image analyzer have an averagencircularity of from 0.935 or more to less than 0.970;nand the toner base particles have an average surfacenroughness of from 5.0 nm or more to less than 35.0 nmnas measured with a scanning probe microscope. Thentoner can enjoy less toner consumption per sheet ofnimages, can achieve a long lifetime in a smallernquantity of toner, and has superior developingnperformance in any environment. |
