Abstract
A method for manufacturing a toner including supplying powder particles containing a binder resin via a plurality of powder-particle supplying units to a treating chamber, the treating chamber having a cylindrical inner peripheral surface, heat treating the powder particles in the treating chamber by supplying hot air into the treating chamber, wherein a temperature of the hot air supplied into the treating chamber is 100.0° C. or higher and 200.0° C. or lower, and adjusting a humidity of the hot air so that a relative humidity of the hot air supplied into the treating chamber is 3.0% or more and 80.0% or less.
