One embodiment of the present invention can provide a developer capable of reducing the influence of image history and suppressing the occurrence of carrier adhesion even when used for a long period of time. In one embodiment of the present invention, a developer includes a toner and a carrier, and the toner includes base particles including a colorant, a release agent, and a binder resin, and a non-spherical external additive. In the carrier, magnetic particles are dispersed in a binder resin, and irregularities having an average height difference of 0.02 μm to 3.0 μm are formed on the surface. [Selection figure] None |
