Two-Component Developer |
| abstract |
A magnetic carrier obtained by coating a magnetic core with a resin; And a toner, wherein the magnetic core contains at least a ferrite component and at least one oxide selected from the group consisting of SiO 2 and Al 2 O 3 ; The oxide content is 4.0% by mass or more and 40.0% by mass or less with respect to the magnetic core; The specific resistance of the magnetic core when applying 1,000 V / cm is 5.0 × 10 4 Ω · cm or more and 5.0 × 10 8 Ω · cm or less; The strength of magnetization at 79.6 kA / m of the magnetic carrier is 40.0 Am 2 / kg or more and 65.0 Am 2 / kg or less, and the residual magnetization after application of an external magnetic field of 79.6 kA / m is 3.0 Am 2 / kg or less; The toner is provided with a two-component developer having a weight average particle diameter (D4) of 3.0 µm or more and 10.0 µm or less and an average circularity of 0.940 or more and 0.990 or less. |
