Patent ID: 8921023

Claim:
A magnetic carrier comprising: a magnetic substance-dispersed resin carrier core, which contains a magnetic substance and a binding resin, and a coating resin on a surface thereof, wherein: the magnetic substance-dispersed resin carrier core has a resistivity Rk at 1000 V/cm of 5.0×10 6 Ω·cm or more and 8.0×10 7 Ω·cm or less, the magnetic substance i) has a number average particle diameter of 0.20 μm or more and 0.35 μm or less, and ii) comprises magnetic-substance particles having a shape with vertexes and having a particle diameter of 0.53 μm or more in an amount of 10.0 vol % or more and 32.0 vol % or less based on a total amount of the magnetic substance; and wherein: when analyzing an element in the magnetic substance-dispersed resin carrier core by a fluorescent X-ray analysis and calculating the contents of Fe element and Zn element therein by fundamental parameter quantitative method, i) an Fe 2 O 3 content is 98.00% by mass or more, and ii) a ZnO content is 0.06% by mass or more and 0.50% by mass or less, with respect to the total amount by mass of all the detected elements provided that all the detected elements are in oxide form.
