Abstract
A durable two-component developing agent for electrophotography is provided that can not only suppress scattering of a toner into an inside of an apparatus but also obtain a high image density and can stably obtain a high-quality image even in use for a long period of time. The two-component developing agent for electrophotography includes a toner, and a carrier. The carrier contains a core material and a coating layer formed on a surface thereof. The coating layer is a silicone resin coating layer containing dendritic titanium oxide. Therefore, it is possible to not only suppress scattering of the toner but also obtain a sufficient image density and to form a high-quality image without reducing the image density even in use for a long period of time.
