Magnetic carrier, two-component developer, and replenishment developer
Abstract:
A magnetic carrier includes a magnetic core and a coating resin that covers a surface of the magnetic core. The coating resin includes a resin A and a resin B. A content of the resin A is 1 to 50% by mass, and a content of the resin B is 50 to 99% by mass, with respect to the coating resin. The resin A has a particular unit Y1 and a particular unit Y2, and the resin B contains 0.1% by mass or less of the particular unit Y2. When a mass of the resin A is represented by X, a mass of the unit Y1 is represented by Ma, and a mass of the unit Y2 is represented by Mb, 0.90≤(Ma+Mb)/X≤1.00 and 1.00≤Ma/Mb≤30.0 are satisfied, and also 0≤|SPa−SPb|≤2.0 is satisfied.
