Abstract
The present invention relates to a toner and a two-component developer which can produce high quality images with decreasing the dependence on environment and the back ground during continuous printing of a large number of sheets. The toner includes toner particles including a binder resin as a main component thereof and having particle surfaces deposited with titanium oxide particles, the surfaces of which are treated with at least isobutyl trimethoxy silane and trimethyl siloxysilicate. The two-component developer includes the toner and a carrier including core particles, the surfaces of which are coated with a resin coating agent including 5 to 20 percent by weight of carbon black, relative to the total weight of the resin coating agent.
