Zusammenfassung:	In a two-component developer, external additive particles of toner particles include resin particles. The resin particles contain a crosslinked resin including a repeating unit derived from a crosslinking agent. Carrier particles each include a carrier core and a coat layer covering a surface of the carrier core. The coat layers contain a coating resin and barium titanate particles. The coating resin includes a silicone resin. The barium titanate particles have a number average primary particle diameter within a range of 100 nm to 500 nm. The barium titanate particles have a content within a range of 5 parts by mass to 45 parts by mass relative to 100 parts by mass of the coating resin. A rate of a mass of the coat layers to a mass of the carrier cores is greater than 0.0% by mass and no greater than 4.9% by mass. The carrier cores have a shape factor within a range of 34.0% to 85.0%.
