The invention provides toner for a two-component type developer containing toner particles including a binder resin and magnetic powder dispersed in the binder resin. The binder resin in the toner is prepared from a composition including at least one of (1) a polymer having an anionic group and a wax grafted portion and (2) a mixture of a polymer having an anionic group and a polymer having a wax grafted portion. The magnetic powder is contained in the toner particles at a proportion ranging between 0.1 and 5 parts by weight per 100 parts by weight of the binder resin. <IMAGE>
