Abstract
A developer carrying member is provided the surface layer of which can make a developer stable by controlling its triboelectric charging strongly and which can maintain a high image quality over a long period of time even where a developer made highly spherical-particle or a small-particle developer is used. The developer carrying member has a substrate and a surface layer. The surface layer is a cured product of a resin composition containing a binder resin, conductive particles, a quaternary ammonium salt and an azo metal complex compound, the binder resin has in the molecular structure at least one structure selected from the group consisting of an —NH2 group, an ═NH group and an —NH— linkage, and the azo metal complex compound is a compound represented by the formula (1) as defined in the specification.
