Carrier and two-component developer

A carrier comprising carrier particles, wherein

• the carrier particles include first carrier particles and second carrier particles,
• the first carrier particles each include a first carrier core and a first coat layer covering a surface of the first carrier core,
• the second carrier particles each include a second carrier core and a second coat layer covering a surface of the second carrier core,
• the first coat layers contain no fatty acid metal salt,
• the second coat layers contain a coat layer binder resin and a fatty acid metal salt,
• the second coat layers contain the fatty acid metal salt in a proportion of at least 85% by mass and no greater than 95% by mass relative to a total mass of the second coat layers, and
• the second carrier particles are contained in a proportion of at least 7% by mass and no greater than 15% by mass relative to a total mass of the first carrier particles and the second carrier particles.
