Magnetic carrier, two-component developer, replenishing developer, and image forming method

A two-component developer comprising

• a toner having a toner particle including a binder resin, and
• a magnetic carrier,
• wherein
• the magnetic carrier comprises a magnetic carrier particle,
• the magnetic carrier particle has
• a magnetic carrier core and
• a resin coating layer formed on a surface of the magnetic carrier core,
• wherein
• the resin coating layer includes a resin component including a resin A and a resin B,
• the resin A is a copolymer of monomers including
• (a) a (meth)acrylic acid ester monomer having an alicyclic hydrocarbon group, and
• (b) a macromonomer containing a polymer portion and a reactive portion bound to the polymer portion, wherein
• the polymer portion has a polymer of at least one monomer selected from the group consisting of methyl acrylate, methyl methacrylate, butyl acrylate, butyl methacrylate, 2-ethylhexyl acrylate and 2-ethylhexyl methacrylate, and
• the reactive portion has a reactive C—C double bond, the resin B is a copolymer of monomers including
• (c) a styrene-based monomer, and
• (d) a (meth)acrylic acid ester monomer having a hydroxy group and represented by a following formula (1), and
• based on the resin components of the resin coating layer, the amount of the resin A is from 20% by mass to 99% by mass, and the amount of the resin B is from 1% by mass to 80% by mass,
• wherein, R represents H or CH3, and n represents an integer of from 1 to 8.
