A carrier includes carrier particles. 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 layer contains 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 from 85 mass % to 95 mass % relative to a total mass of the second coat layers. The second carrier particles are contained in a proportion of from 7 mass % to 15 mass % relative to a total mass of the first carrier particles and the second carrier particles.
