A toner contains a coloring agent and a binder including a wax and an ethyl polysaccharide, which has D-glucose units linked together by a linkage of 1,2-, 1,3-, 1,4-, or 1,6-glycosidic bond with an alpha configuration, or by a linkage of 1,2-, 1,3-, 1,4- or 1,6-glycosidic bond with a beta configuration, with at least one alcohol hydroxyl group in each D-glucose unit being ethyl-etherified. A one-component developer for electrophotography is prepared using the toner, and a two-component developer is prepared by the combination of the toner and a carrier.
