A toner is composed primarily of toner particles containing at least a binder resin, a colorant and a wax, and inorganic fine particles. The binder resin is one which has at least a polyester unit and is synthesized by using as a catalyst one or more compounds selected from titanium chelate compounds each having a specific structure and hydrates of the titanium chelate compounds. The toner has superior fixing performance and high-temperature anti-offset properties and is superior in charge stability even when used for a long time.
