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 includes a magnetic carrier particle having 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 represented by a following formula (1), and
• in a molecular weight distribution of a tetrahydrofuran soluble component of the resin component contained in the resin coating layer, a peak derived from the resin B is present in a molecular weight range of from 1000 to 9500,
• in the formula (1), R1 represents H or CH3, and n represents an integer of from 2 to 8.
