An embodiment of the present invention can provide a carrier capable of reducing the influence of image history even when used for a long period of time and suppressing the occurrence of carrier adhesion. In one embodiment of the present invention, in a carrier, a protective layer is formed on the surface of a core particle, the core particle includes a ferromagnetic iron oxide particle and a first resin, and has a ten-point average roughness. Rz is 0.3 μm or more and 2.0 μm or less, the first resin is a phenol resin, the protective layer includes conductive particles and a second resin, and the mass ratio of the conductive particles to the second resin Is 1 or more and 3 or less.
