MAGNETIC CARRIER, TWO-COMPONENT DEVELOPER, AND DEVELOPER FOR REPLENISHMENT
摘要:
The magnetic carrier is a magnetic carrier including a magnetic core and a coating resin configured to coat the surface of the magnetic core, wherein the coating resin contains a graft resin A and a graft resin B, wherein the coating resin (i) contains 1.0 mass% or more and 50.0 mass% or less of the graft resin A, and (ii) contains 50.0 mass% or more and 99.0 mass% or less of the graft resin B, wherein the graft resin A has a unit Y1 represented by the following formula (1) and a unit Y2 represented by the following formula (2), and wherein the graft resin B (i) is a comb-shaped polymer having, as a branch, at least one moiety selected from, for example, a styrene-based polymer moiety and a (meth)acrylate-based polymer moiety, and (ii) contains the polysiloxane structure moiety at a content of 0.1 mass% or less.
